THE X-RAY CRYSTAL STRUCTURE OF SKY1P, AN SR PROTEIN KINASE IN YEASTTHE X-RAY CRYSTAL STRUCTURE OF SKY1P, AN SR PROTEIN KINASE IN YEAST
Structural highlights
Function[SKY1_YEAST] Constitutively active kinase, specifically and sequentially phosphorylates serine/arginine (SR)-type shuttling mRNA binding proteins in their RS dipeptide repeats.[1] Evolutionary Conservation Check, as determined by ConSurfDB. You may read the explanation of the method and the full data available from ConSurf. Publication Abstract from PubMedSky1p is the only member of the SR protein kinase (SRPK) family in Saccharomyces cerevisiae. SRPKs are constitutively active kinases that display remarkable substrate specificity and have been implicated in RNA processing. Here we present the three-dimensional structure of a fully active truncated Sky1p. Analysis of the structure and structure-based functional studies reveal that the C-terminal tail, an unusual Glu residue located in the P+1 loop, and a unique mechanism for the positioning of helix alpha C act together to render Sky1p constitutively active. We have modeled a substrate peptide bound to Sky1p. The modeled complex combined with mutagenesis studies illustrate the molecular basis for substrate recognition by this kinase and suggest a mechanism by which SRPKs catalyze a sequential phosphorylation reaction of the consecutive RS dipeptide repeats characteristic of mammalian SRPK substrates. The structure of Sky1p reveals a novel mechanism for constitutive activity.,Nolen B, Yun CY, Wong CF, McCammon JA, Fu XD, Ghosh G Nat Struct Biol. 2001 Feb;8(2):176-83.
