Uniprot Id

Q96Q27

Target Species

Human

Target Name

ASB2

Target Full Name

Ankyrin repeat and SOCS box protein 2

Target Function

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. Mediates Notch-induced ubiquitination and degradation of substrates including TCF3/E2A and JAK2. Required during embryonic heart development for complete heart looping. Required for cardiomyocyte differentiation.; Involved in myogenic differentiation and targets filamin FLNB for proteasomal degradation but not filamin FLNA. Also targets DES for proteasomal degradation. Acts as a negative regulator of skeletal muscle mass.; Targets filamins FLNA and FLNB for proteasomal degradation. This leads to enhanced adhesion of hematopoietic cells to fibronectin. Required for FLNA degradation in immature cardiomyocytes which is necessary for actin cytoskeleton remodeling, leading to proper organization of myofibrils and function of mature cardiomyocytes. Required for degradation of FLNA and FLNB in immature dendritic cells (DC) which enhances immature DC migration by promoting DC podosome formation and DC-mediated degradation of the extracellular matrix. Does not promote proteasomal degradation of tyrosine-protein kinases JAK1 or JAK2 in hematopoietic cells.

Target Subcellular Location

Cytoplasm, cytoskeleton, stress fiber.; [Isoform 1]: Cytoplasm, myofibril, sarcomere, Z line.

Target Protein Families

Ankyrin SOCS box (ASB) family

Target Tissue Specificity

[Isoform 1]: Expressed in muscle cells.; [Isoform 2]: Expressed in hematopoietic cells.

Target Synonyms

ASB2Ankyrin repeat and SOCS box protein 2; ASB-2

Target Background

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.
