Function

Component of the nuclear pore complex (NPC), a complex required for the trafficking across the nuclear envelope. Functions as a scaffolding element in the nuclear phase of the NPC essential for normal nucleocytoplasmic transport of proteins and mRNAs, plays a role in the establishment of nuclear-peripheral chromatin compartmentalization in interphase, and in the mitotic spindle checkpoint signaling during mitosis. Involved in the quality control and retention of unspliced mRNAs in the nucleus; in association with NUP153, regulates the nuclear export of unspliced mRNA species bearing constitutive transport element (CTE) in a NXF1- and KHDRBS1-independent manner. Negatively regulates both the association of CTE-containing mRNA with large polyribosomes and translation initiation. Does not play any role in Rev response element (RRE)-mediated export of unspliced mRNAs. Implicated in nuclear export of mRNAs transcribed from heat shock gene promoters; associates both with chromatin in the HSP70 promoter and with mRNAs transcribed from this promoter under stress-induced conditions. Modulates the nucleocytoplasmic transport of activated MAPK1/ERK2 and huntingtin/HTT and may serve as a docking site for the XPO1/CRM1-mediated nuclear export complex. According to some authors, plays a limited role in the regulation of nuclear protein export (PubMed:11952838, PubMed:22253824). Also plays a role as a structural and functional element of the perinuclear chromatin distribution; involved in the formation and/or maintenance of NPC-associated perinuclear heterochromatin exclusion zones (HEZs). Finally, acts as a spatial regulator of the spindle-assembly checkpoint (SAC) response ensuring a timely and effective recruitment of spindle checkpoint proteins like MAD1L1 and MAD2L1 to unattached kinetochore during the metaphase-anaphase transition before chromosome congression. Its N-terminus is involved in activation of oncogenic kinases.

Activity summary

The translocated promoter region protein (TPR) also known commonly as 'horse TPR' consists of approximately 267 kDa. TPR is a nucleoporin protein primarily expressed in the nuclear envelope of eukaryotic cells. It serves as a structural and regulatory component of the nuclear pore complex (NPC) playing a critical role in nucleocytoplasmic transport. A structural scaffold TPR facilitates the organization and entrance of nuclear transport receptors and cargo molecules through the NPC impacting the efficient movement of proteins and RNA across the nuclear membrane.

Biological function summary

TPR interacts with other nucleoporins within the NPC to ensure proper nuclear function. TPR is integral in maintaining the spatial organization and transport selectivity within the nucleoplasm-cytoplasm interface by forming an interaction network with other proteins like NUP98 and NUP153. TPR functions as part of the NPC assembly contributing to essential cellular processes like gene expression regulation and DNA repair by participating in chromatin organization.

Pathways

TPR integrates into the nuclear transport pathway and it also plays a role in the MAPK signaling pathway. Within the nuclear transport pathway TPR facilitates the proper translocation of molecules necessary for downstream cellular functions. In the MAPK signaling pathway it synchronizes with other proteins like ERK to control processes such as proliferation and differentiation. TPR's interaction with these pathways positions it as an important player in cellular communication and response.

Associated diseases and disorders

TPR has connections to cancer and neurodegenerative diseases. In various cancers abnormal TPR function impacts cell growth and proliferation by altering nuclear transport dynamics. Additionally it associates with Alzheimer's disease through its interactions with tau protein affecting neuronal function. These connections make TPR a significant target for understanding disease mechanisms and developing therapeutic interventions.

    EBLN1 does not interact with the Cyclin B1-CDK1 complex, but does interact with TPR.(A) Immunoprecipitation of endogenous EBLN1 from HeLa cells probed with either EBLN1 or Cyclin B1 antibodies. Agarose beads incubated with cell extracts and IgG was used as a negative control for non-specific protein binding. Black arrow indicates FLAG-tagged EBLN1 band. (B) Immunoprecipitation (IP) of endogenous Cyclin B1 from asynchronous (upper panel) or mitotic (lower panel) FLAG-EBLN1 expressing HeLa cells probed with the indicated antibodies. The minus tetracycline (−Tet) samples (uninduced expression of FLAG-EBLN1) serve as negative controls for non-specific protein binding. (C) Immunoprecipitation of FLAG-EBLN1 from tetracycline-inducible HeLa cells probed with the indicated antibodies. Minus tetracycline samples serve as negative controls for non-specific protein binding. (D) Upper panel shows EBLN1 and FLAG western blots of eluates from FLAG-EBLN1 expressing tet-inducible HeLa cells. Lower panel shows a SYPRO Ruby stained polyacrylamide gel of FLAG eluates shown in the upper panel. Black arrow indicates FLAG-tagged EBLN1 band. (E) Table showing some of the most prevalent proteins co-immunoprecipitating with FLAG-EBLN1 as determined by proteomic analyses of the eluates shown in (E). The number of unique peptides for each protein is shown for both uninduced and induced (−Tet and + Tet) samples to highlight enrichment in FLAG-EBLN1 eluates (+Tet samples), along with the respective peptide coverage for each protein identified. (F) Indicated western blots on inputs (left panel), GFP immunoprecipitations and TPR immunoprecipitations (right panels) in stable tetracycline-inducible GFP-EBLN1 expressing HeLa cell lines. Arrows highlight GFP-EBLN1 band in each IP. Note that a longer exposure is shown for the TPR IPs compared with the GFP IPs. (G) TPR western blots of immunoprecipitated endogenous TPR from HeLa cells transfected with the indicated siRNA. Arrows highlight TPR isoforms (upper panel) and TPR-specific band in EBLN1 IPs (lower panel), which are reduced in cells transfected with TPR siRNA. Note that the TPR antibody is not capable of recognising endogenous TPR in the input lanes, only purified TPR in the IP lanes.
