Previous GeneCards Identifiers for ASB2 Gene
This gene encodes a member of the ankyrin repeat and SOCS box-containing (ASB) protein family. These proteins play a role in protein degradation by coupling suppressor of cytokine signalling (SOCS) proteins with the elongin BC complex. The encoded protein is a subunit of a multimeric E3 ubiquitin ligase complex that mediates the degradation of actin-binding proteins. This gene plays a role in retinoic acid-induced growth inhibition and differentiation of myeloid leukemia cells. Alternatively spliced transcript variants encoding multiple isoforms have been observed for this gene. [provided by RefSeq, Jan 2011]

UniProtKB/Swiss-Prot Summary for ASB2 Gene
Substrate-recognition component of a SCF-like ECS (Elongin-Cullin-SOCS-box protein) E3 ubiquitin-protein ligase complex which mediates the ubiquitination and subsequent proteasomal degradation of target proteins.
Isoform 1: Enhances adhesion of hematopoietic cells to fibronectin through targeting of filamins FLNA and FLNB for proteasomal degradation, it is transiantly expressed during hematopoietic cell differentiation.
Isoform 2: Involved in myogenic differentiation and targets filamin FLNB for proteasomal degradation but not filamin FLNA.
