Protein tyrosine phosphatase TbPTP1:A molecular switch controlling life cycle differentiation in trypanosomes [PDF]

open access: yes, 2006
Differentiation in African trypanosomes (Trypanosoma brucei) entails passage between a mammalian host, where parasites exist as a proliferative slender form or a G0-arrested stumpy form, and the tsetse fly.

Tyrosine phosphorylation of myosin heavy chain during skeletal muscle differentiation: an integrated bioinformatics approach [PDF]

open access: yes, 2005
Background: Previously it has been shown that insulin-mediated tyrosine phosphorylation of myosin heavy chain is concomitant with enhanced association of C-terminal SRC kinase during skeletal muscle differentiation. We sought to identify putative site(s)

The Vav GEF Family: An Evolutionary and Functional Perspective

open access: yesCells, 2019
Vav proteins play roles as guanosine nucleotide exchange factors for Rho GTPases and signaling adaptors downstream of protein tyrosine kinases. The recent sequencing of the genomes of many species has revealed that this protein family originated in ...

EGF regulates tyrosine phosphorylation and membrane-translocation of the scaffold protein Tks5 [PDF]

open access: yes, 2013
Background: Tks5/FISH is a scaffold protein comprising of five SH3 domains and one PX domain. Tks5 is a substrate of the tyrosine kinase Src and is required for the organization of podosomes/invadopodia implicated in invasion of tumor cells.
