E3 ubiquitin-protein ligase ARIH2 (ARIH2)

The protein contains 493 amino acids for an estimated molecular weight of 57819 Da.

 

E3 ubiquitin-protein ligase, which catalyzes ubiquitination of target proteins together with ubiquitin-conjugating enzyme E2 UBE2L3 (PubMed:16118314, PubMed:17646546, PubMed:19340006, PubMed:24076655). Acts as an atypical E3 ubiquitin-protein ligase by working together with cullin-5-RING ubiquitin ligase complex (ECS complex, also named CRL5 complex) and initiating ubiquitination of ECS substrates: associates with ECS complex and specifically mediates addition of the first ubiquitin on ECS targets (By similarity). The initial ubiquitin is then elongated (By similarity). E3 ubiquitin-protein ligase activity is activated upon binding to neddylated form of the ECS complex (PubMed:24076655). Mediates 'Lys-6', 'Lys-48'- and 'Lys-63'-linked polyubiquitination (PubMed:16118314, PubMed:17646546, PubMed:19340006). May play a role in myelopoiesis (PubMed:19340006). (updated: Dec. 11, 2019)

CLONING

Zinc-binding cysteine and histidine residues that form a 3-dimensional structure, stabilized by zinc, are found in protein-interacting motifs in LIM (e.g., LMO1; 186921), RING (e.g., RING1; 602045), or LAP (e.g., AF10; 602409) finger-containing proteins. Van der Reijden et al. (1999) identified ARIH2, which they termed TRIAD1, a 493-amino acid nuclear protein upregulated during retinoic acid-induced granulocytic differentiation of acute promyelocytic leukemia cells. ARIH2 contains 2 RING fingers flanking a conserved cysteine-rich (C6HC) domain the authors designated DRIL (double RING finger-linked domain); 2 C-terminal coiled-coil domains; and an acidic N-terminal region. The DRIL domain with its 2 flanking RING fingers, collectively referred to by the authors as the TRIAD (2 RING fingers and DRIL) domain, spans approximately 200 amino acids and was identified, with a preserved order and distance, in more than 20 eukaryotic proteins.

MAPPING

The International Radiation Hybrid Mapping Consortium mapped the ARIH2 gene to chromosome 3 (TMAP WI-11545). ... More on the omim web site
