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.
