Biochemical Activity (Dephosphorylation)

An interaction is inferred from the biochemical effect of one protein upon another, for example, GTP-GDP exchange activity or phosphorylation of a substrate by a kinase. The bait protein executes the activity on the substrate hit protein. A Modification value is recorded for interactions of this type with the possible values Phosphorylation, Ubiquitination, Sumoylation, Dephosphorylation, Methylation, Prenylation, Acetylation, Deubiquitination, Proteolytic Processing, Glucosylation, Nedd(Rub1)ylation, Deacetylation, No Modification, Demethylation.

Specific dephosphorylation of the Lck tyrosine protein kinase at Tyr-394 by the SHP-1 protein-tyrosine phosphatase.

Chiang GG, Sefton BM

The protein-tyrosine phosphatase SHP-1 has been shown to be a negative regulator of multiple signaling pathways in hematopoietic cells. In this study, we demonstrate that SHP-1 dephosphorylates the lymphoid-specific Src family kinase Lck at Tyr-394 when both are transiently co-expressed in nonlymphoid cells. We also demonstrate that a GST-SHP-1 fusion protein specifically dephosphorylates Lck at Tyr-394 in vitro. Because phosphorylation ... [more]
