Abstract
BACKGROUND:Post-translational (PT) modification in cells regulates many intracellular events like signal transduction,transcription,cell cycle,protein quality control,apoptosis and cellular development.Ubiquitination is one of the PT modifications which functions as a marker for degradation of target proteins by the proteasome and as a regulatory mechanism for several signalling pathways.The ubiquitination mechanism requires multiple enzymes,including E 1,E2,and E3 ligases.Among them,E3 ligases play a major role in recognizing target proteins and an essential feature of protein homeostatic mechanisms within the cell.Most of the ASB (ankyrin repeat SOCS box) proteins function as RING family of E3 ubiquitin ligases characterized by the presence of two conserved domains N-terminal ankyrin repeat and C-terminal SOCS box domain METHODS and RESULTS:Current studies have shown that some ASBs function as important regulators of several signalling pathways.This review gives an overview of ASB proteins on numerous cellular processes such as insulin signalling,spermatogenesis,myogenesis and in cellular development.Including various pathological situations,such as cancer,primary open-angle glaucoma,and inflammation,indicating that ASBs has important functions in both normal and pathological developmentCONCLUSIONS:This article provides a precise comprehensive focus on ASBs protein structure,its biological functions,and their pathological significance.
