Summary

RNF187 (ring finger protein 187, HGNC:27146) is a protein-coding gene on chromosome 1q42.13, encoding E3 ubiquitin-protein ligase RNF187 (Q5TA31). E3 ubiquitin-protein ligase that acts as a coactivator of JUN-mediated gene activation in response to growth factor signaling via the MAP3K1 pathway, independently from MAPK8.

Enables ubiquitin-protein transferase activity. Involved in positive regulation of DNA-templated transcription; proteasome-mediated ubiquitin-dependent protein catabolic process; and protein ubiquitination. Located in cytosol and nucleoplasm.

Function. E3 ubiquitin-protein ligase that acts as a coactivator of JUN-mediated gene activation in response to growth factor signaling via the MAP3K1 pathway, independently from MAPK8.

Subunit / interactions. Homodimer. Interacts with JUN, independently of JUN phosphorylation. Interacts (via C-terminus) with TRIM7.

Subcellular location. Cytoplasm. Nucleus.

Post-translational modifications. Ubiquitinated; undergoes ‘Lys-48’-linked autoubiquitination in the absence of growth factors and MAP3K1-induced ‘Lys-63’-linked polyubiquitination. ‘Lys-48’-autoubiquitination leads to degradation by the proteasome, while MAP3K1-induced ‘Lys-63’-linked polyubiquitination results in the stabilization of the protein. ‘Lys-48’- and ‘Lys-63’-linked polyubiquitinations occur most probably on the same 3 C-terminal lysine residues (Lys-195, Lys-223 and Lys-224) and are thus mutually exclusive. Other sites of ubiquitination are not excluded. ‘Lys-63’-linked polyubiquitination by TRIM7 in response to growth factor signaling via the MEK/ERK pathway enhances protein stability. Arginine methylation by PRMT1 stabilizes RNF187 by facilitating K63-linked ubiquitin chain formation, and enables dimerization, c-Jun interaction and subsequent AP1 target gene expression.

Domain organisation. The RING-type zinc finger domain is required for E3 ligase activity.

Pathway. Protein modification; protein ubiquitination.
