phosphorylates

Cyclin-dependent kinase 5 (Cdk5) is a serine/threonine kinase that is predominantly active in neuronal tissues. With p25 or p35, Cdk5 phosphorylates a range of proteins, including histone H1 and tau. Cdk5 Substrate acetate is a synthetic peptide (PKTPKKAKKL) corresponding to a sequence of histone H1. It is phosphorylated by Cdk5 with a Km value of 5 µM.

S3 Fragment is a biologically active peptide featuring the amino-terminal phosphorylation site unique to Xenopus ADF/cofilin, which is the target of LIM kinase (LIMK) phosphorylation. LIMK1, a pivotal regulator of the actin cytoskeleton, phosphorylates ADF/cofilin at serine-3, leading to its inactivation. As a segment of the S3 peptide harboring the serine-3 sequence, this fragment serves as a widely recognized competitive inhibitor of LIMK1.
