A protein kinase from Dictyostelium discoideum with an unusual acidic repeat domain

摘要

DdKinX codes for MW3 amino acids which are organized in four regions: the N-terminal catalytic domain, a region containing 30% acidic amino acids, tandem repeals of the motif VKVEEPVEE and the C-terminus. Identity with other protein kinases is 25 to 30%. Descendent trees show thai DdKinX does not belong to any of the known kinase branches.
