Biochemical Activity (Phosphorylation)

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.

Protein kinase C-mediated phosphorylation of the two polybasic regions of synaptotagmin VI regulates their function in acrosomal exocytosis.

Roggero CM, Tomes CN, De Blas GA, Castillo J, Michaut MA, Fukuda M, Mayorga LS

We have previously reported that synaptotagmin VI is present in human sperm cells and that a recombinant protein containing the C2A and C2B domains abrogates acrosomal exocytosis in permeabilized spermatozoa, an effect that was regulated by phosphorylation. In this report, we show that each individual C2 domain blocks acrosomal exocytosis. The inhibitory effect was completely abrogated by phosphorylation of the ... [more]
