Western blot - Anti-Importin4/Imp4 antibody [EPR13660] - BSA and Azide free (AB250306)

This data was developed using the same antibody clone in a different buffer formulation (ab181046).

Lanes 1-4 : Merged signal (red and green). Green - ab181046 observed at 130 kDa. Red - loading control ab8245 observed at 36 kDa.

ab181046 Anti-Importin4/Imp4 antibody [EPR13660] was shown to specifically react with Importin4/Imp4 in wild-type HEK293T cells. Loss of signal was observed when knockout cell line ab266175 (knockout cell lysate ab258005) was used. Wild-type and Importin4/Imp4 knockout samples were subjected to SDS-PAGE. ab181046 and Anti-GAPDH antibody [6C5] - Loading Control (ab8245) were incubated overnight at 4°C at 1 in 1000 dilution and 1 in 20000 dilution respectively. Blots were developed with Goat anti-Rabbit IgG H&L (IRDye® 800CW) preadsorbed (ab216773) and Goat anti-Mouse IgG H&L (IRDye® 680RD) preadsorbed (ab216776) secondary antibodies at 1 in 20000 dilution for 1 hour at room temperature before imaging.

Supplementary information

This supplementary information is collated from multiple sources and compiled automatically.

Importin4 (Imp4) also known as Ipo4 is a nuclear import receptor with an approximate mass of 130 kDa. This protein facilitates the transport of molecules such as ribosomal proteins and histones into the nucleus. Expression of Importin4 occurs in various tissues including the brain testis and liver. Importin4 plays a significant mechanical role by recognizing nuclear localization signals on cargo molecules and mediating their translocation across the nuclear envelope.
Biological function summary

Importin4 functions as part of the nuclear transport system a complex network essential for cellular operations. Importin4 interacts with the nuclear pore complex to enable import of specific protein cargo into the nucleus. By partnering with karyopherins and Ran-GTPase Importin4 participates in the active transport mechanism ensuring the correct localization of proteins that are critical to genomic regulation processes.

Pathways

Importin4 plays a role in the nuclear transport pathway and is associated with the ribosome biogenesis pathway. This protein works alongside proteins like Ran-GTPase enhancing the translocation of ribosomal components pivotal for cellular growth and protein synthesis. Importin4 also aids in the shuttling of histones which are essential to chromatin assembly and DNA transcription regulation.

Importin4 has connections to cancer and neurodegenerative diseases. Altered expression and mutations in Importin4 may disrupt cellular homeostasis and nuclear transport linking it to tumorigenesis. Additionally associations with proteins such as karyopherin alpha importers indicate its involvement in pathological states affecting the nervous system potentially contributing to conditions such as Alzheimer's disease. Understanding Importin4's interactions could provide insights into these complex diseases.

Target data

Nuclear transport receptor that mediates nuclear import of proteins, such as histones, RPS3A, TNP2 and VDR (PubMed : 11823430, PubMed : 16207705, PubMed : 17682055, PubMed : 21454524). Serves as receptor for nuclear localization signals (NLS) in cargo substrates (PubMed : 11823430, PubMed : 16207705). Is thought to mediate docking of the importin/substrate complex to the nuclear pore complex (NPC) through binding to nucleoporin and the complex is subsequently translocated through the pore by an energy requiring, Ran-dependent mechanism (PubMed : 11823430, PubMed : 16207705). At the nucleoplasmic side of the NPC, Ran binds to the importin, the importin/substrate complex dissociates and importin is re-exported from the nucleus to the cytoplasm where GTP hydrolysis releases Ran (PubMed : 11823430). The directionality of nuclear import is thought to be conferred by an asymmetric distribution of the GTP- and GDP-bound forms of Ran between the cytoplasm and nucleus (PubMed : 11823430). Mediates the nuclear import of the histone H3-H4 dimer when in complex with ASF1 (ASF1A or ASF1B) (PubMed : 21454524, PubMed : 29408485). Mediates the ligand-independent nuclear import of vitamin D receptor (VDR) (PubMed : 16207705). In vitro, mediates the nuclear import of human cytomegalovirus UL84 by recognizing a non-classical NLS (PubMed : 12610148).
