Description
TXK or RLK is a member of the TEC family of non-receptor tyrosine kinases. TXK is expressed in T-cells and is an important component of signaling pathways downstream of lymphocyte antigen receptor.TXK is phosphorylated in response to T-cell receptor stimulation and can be activated by phosphorylation by Src family kinases. However, TXK is phosphorylated independent of PI-3K activity. Excessive TXK protein expression is seen in patients with Behcets disease. Over production of TXK leads to increased Th1 cell function that is involved in the pathogenesis of Behcet?s disease
