The ARIH2 Polyclonal Antibody (PAC047306) is a valuable tool for researchers studying the ARIH2 protein, a key player in the ubiquitin-proteasome system. This antibody, generated in rabbits, has been validated for use in Western blot applications and is highly reactive with human samples.ARIH2 is an E3 ubiquitin-protein ligase that plays a crucial role in protein degradation and regulation. By targeting specific proteins for degradation via the ubiquitin-proteasome system, ARIH2 is involved in various cellular processes, including cell cycle regulation and immune response modulation.
With its specificity and reliability in detecting ARIH2 protein, this antibody is essential for researchers investigating the role of ARIH2 in cellular pathways, protein degradation mechanisms, and disease development. Its application in immunology and cancer research makes it a valuable tool for uncovering new therapeutic targets and potential treatment strategies.

Background:
E3 ubiquitin-protein ligase, which catalyzes ubiquitination of target proteins together with ubiquitin-conjugating enzyme E2 UBE2L3. 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. Mediates 'Lys-6', 'Lys-48'-and 'Lys-63'-linked polyubiquitination. May play a role in myelopoiesis.

NCBI Summary:
The protein encoded by this gene is an E3 ubiquitin-protein ligase that polyubiquitinates some proteins, tagging them for degradation. The encoded protein upregulates p53 in some cancer cells and may inhibit myelopoiesis. Several transcript variants encoding different isoforms have been found for this gene, although the full-length nature of some of them have not been determined yet. [provided by RefSeq, Nov 2015]
