ASB2 (Ankyrin Repeat and SOCS Box Containing 2): ASB2 belongs to the ASB family involved in the ubiquitin-proteasome pathway, which regulates protein degradation. ASB2 works by targeting specific proteins for ubiquitination and subsequent breakdown, helping to control protein levels within cells. It plays a key role in regulating actin cytoskeleton dynamics and muscle function. Additionally, ASB2 is associated with regulating hematopoietic stem cell differentiation and may influence the development of certain leukemias and muscular disorders. Dysregulation of ASB2 can disrupt normal cellular homeostasis.
