Molecular classification
Enzyme, Protein Kinase, Tyrosine Kinase, Non-receptor tyrosine kinase, Src family kinase
01

Overview

Lyn is a non-receptor tyrosine kinase belonging to the Src family. It plays a crucial role in various cellular processes, particularly in hematopoietic cells, by regulating signaling pathways involved in cell proliferation, survival, differentiation, migration, and immune responses. It acts as a rheostat modulating both activating and inhibitory signals, making it a key regulator of immune tolerance. Aberrant Lyn activity is implicated in various diseases, including autoimmune disorders and cancers.
