| Post Translational Modifications | Ubiquitinated.mediated by AREL1 and leading to its subsequent proteasomal degradation. Ubiquitination is dependent on its phosphorylation at Ser-52, by PKC. Ubiquitination is stimulated by LPS. Phosphorylation at Ser-52 by PKC facilitates its ubiquitination and proteasomal degradation. |
| Function | Substrate-recognition component of a cullin-5-RING E3 ubiquitin-protein ligase complex (ECS complex, also named CRL5 complex), which mediates the ubiquitination and subsequent proteasomal degradation of target proteins, such as EPOR and GHR. Specifically recognizes and binds phosphorylated proteins via its SH2 domain, promoting their ubiquitination. The ECS(SOCS2) complex acts as a key regulator of growth hormone receptor (GHR) levels by mediating ubiquitination and degradation of GHR, following GHR phosphorylation by JAK2. The ECS(SOCS2) also catalyzes ubiquitination and degradation of JAK2-phosphorylated EPOR. |
