Recombinant Human CBL

Background

CBL is an E3 ubiquitin ligase that plays a crucial role in regulating signal transduction pathways, particularly those associated with receptor tyrosine kinases (RTKs) like the epidermal growth factor receptor (EGFR) and platelet-derived growth factor receptor (PDGFR). CBL mediates the ubiquitination of target proteins, leading to their degradation via the proteasome, and regulates the receptor's internalization and downregulation. This process ensures the proper termination of signaling, which is important for cellular processes such as growth, differentiation, and survival. Dysregulation of CBL activity has been implicated in various cancers, as uncontrolled signaling due to deficient ubiquitination can result in unchecked cell proliferation and survival.
