Rabbit anti-Human NPLOC4 Polyclonal Antibody

Uniprot Id

Q8TAT6

Target Species

Human

Target Name

NPLOC4

Target Full Name

Nuclear protein localization protein 4 homolog

Target Function

The ternary complex containing UFD1, VCP and NPLOC4 binds ubiquitinated proteins and is necessary for the export of misfolded proteins from the ER to the cytoplasm, where they are degraded by the proteasome. The NPLOC4-UFD1-VCP complex regulates spindle disassembly at the end of mitosis and is necessary for the formation of a closed nuclear envelope. Acts as a negative regulator of type I interferon production via the complex formed with VCP and UFD1, which binds to DDX58/RIG-I and recruits RNF125 to promote ubiquitination and degradation of DDX58/RIG-I.

Target Subcellular Location

Cytoplasm, cytosol. Endoplasmic reticulum. Nucleus.

Target Protein Families

NPL4 family

Target Tissue Specificity

Expressed at highest levels in brain, heart, skeletal muscle, kidney and fetal liver.

Target Background

Predicted to enable ATPase binding activity; ubiquitin binding activity; and ubiquitin protein ligase binding activity. Predicted to contribute to K48-linked polyubiquitin modification-dependent protein binding activity and K63-linked polyubiquitin modification-dependent protein binding activity. Involved in negative regulation of RIG-I signaling pathway; negative regulation of type I interferon production; and proteolysis involved in cellular protein catabolic process. Located in nucleus. Part of UFD1-NPL4 complex and VCP-NPL4-UFD1 AAA ATPase complex.
