DmSrc activity has been detected using immunoprecipitates prepared with anti-C-terminal peptide or anti-N-terminal fusion protein antibodies. DmSrc autophosphorylation (at Y434 and elsewhere), phosphorylation of polyjGlu, Ala, Tyr), and phosphorylation of histone (type VII-S, Sigma) has also ...
Protein kinases play key roles in cellular functions. They are involved in many cellular functions including; signal transduction, cell cycle regulation, cell division, and cell differentiation. Alterations of protein kinase by gene amplification, mutation or viral factors often induce tumor formation and...

Protein tyrosine kinases (PTKs) are a class of proteins with tyrosine kinase activity that phosphorylate tyrosine residues of critical molecules in signaling pathways. Their basal function is essential for maintaining normal cell growth and differentiation. However, aberrant activation of PTKs caused by ...

Bruton's tyrosine kinase is acytoplasmic proteini.e. critical for downstream B-cell receptor signaling. The pharmacologic inhibition of BTK results in anti-tumor activity in several B-cellmalignancies, includingMCL. At present, 3 irreversibleBTK inhibitors–ibrutinib,acalabrutinib, andzanubrutinib– ...
