Rabbit anti-Human CDK5RAP3 Polyclonal Antibody

Uniprot Id

Q96JB5

Target Species

Human

Target Name

CDK5RAP3

Target Full Name

CDK5 regulatory subunit-associated protein 3

Target Function

Substrate adapter for ufmylation, the covalent attachment of the ubiquitin-like modifier UFM1 to substrate proteins, in response to endoplasmic reticulum stress. Negatively regulates NF-kappa-B-mediated gene transcription through the control of RELA phosphorylation. Probable tumor suppressor initially identified as a CDK5R1 interactor controlling cell proliferation. Also regulates mitotic G2/M transition checkpoint and mitotic G2 DNA damage checkpoint. Through its interaction with CDKN2A/ARF and MDM2 may induce MDM2-dependent p53/TP53 ubiquitination, stabilization and activation in the nucleus, thereby promoting G1 cell cycle arrest and inhibition of cell proliferation. May also play a role in the rupture of the nuclear envelope during apoptosis. May regulate MAPK14 activity by regulating its dephosphorylation by PPM1D/WIP1. Required for liver development.; (Microbial infection) May be negatively regulated by hepatitis B virus large envelope protein mutant pre-s2 to promote mitotic entry.

Target Background

This gene encodes a protein that has been reported to function in signaling pathways governing transcriptional regulation and cell cycle progression. It may play a role in tumorigenesis and metastasis. A pseudogene of this gene is located on the long arm of chromosome 20. Alternative splicing results in multiple transcript variants that encode different isoforms.
