RNF157

RNF157 (Ring Finger Protein 157) is a Protein Coding gene. An important paralog of this gene is MGRN1.

Ring Finger Protein 157

E3 ubiquitin ligase that ubiquitinates APBB1 for its degradation by the proteasome and thus prevents apoptosis and promotes survival of neurons (PubMed:25342469).
Has a dual role in neurons as it is also required for dendrite growth and maintenance for which its ligase activity is not critical (PubMed:25342469).
May act as a scaffold molecule to regulate this process (PubMed:25342469).
Acts as a downstream effector of the interconnected PI3K and MAPK signaling pathways and thus participates in the regulation of the cell cycle (PubMed:28655764).

Phosphorylation at Ser-660, Ser-661, Ser-662 and Ser-663 downstream of the PI3K and MAPK pathways influences the E3 ligase activity and stability of RNF157 during the cell cycle in an anaphase-promoting complex/cyclosome-CDH1-dependent manner (PubMed:28655764).
