Description

Src is a ubiquitously expressed, non-receptor tyrosine kinase that plays a pivotal role in numerous cellular processes such as proliferation, migration, and transformation. Due to its critical function in regulating signal transduction pathways, Src activity is tightly controlled through reversible phosphorylation and dephosphorylation events and down-regulation by ubiquitin-dependent degradation. Dysfunction of Src, through overexpression or increased activation has profound effects on basic cellular functions. Elevated Src expression and/or activation is evident across a wide range of solid tumour types and has been strongly implicated in the development, maintenance, progression, and metastatic spread of several human cancers, such as prostate, lung, breast, and colorectal cancer.
