Species cross-reactivity is determined by western blot.
Applications Key: W=Western Blotting, IP=Immunoprecipitation, IF-IC=Immunofluorescence (Immunocytochemistry)
Species predicted to react based on 100% sequence homology: Rat.
Specificity / Sensitivity
PITSLRE/CDK11 (D88B3) Rabbit mAb recognizes endogenous levels of total PITSLRE/CDK11 protein. This antibody will detect the full-length (CDK11p110) and is predicted to detect the alternate transcript (CDK11p58) of PITSLRE/CDK11. The antibody is predicted to detect both PITSLREA/CDK11B and PITSLREB/CDK11A.
Source / Purification
Monoclonal antibody is produced by immunizing animals with a synthetic peptide corresponding to residues surrounding Met734 of human PITSLRE/CDK11 protein.
Western blot analysis of extracts from various cell lines using PITSLRE/CDK11 (D88B3) Rabbit mAb.
PITSLRE, alternatively known as cell division kinase 11 (CDK11), is the result of duplication of the CDK11 gene (1). CDK11A and CDK11B encode nearly identical serine/threonine protein kinases, PITSLREB and PITSLREA respectively, both belonging to the p34CDC2 family of protein kinases (2). Full-length PITSLRE/CDK11 (commonly referred to as CDK11p110) is expressed ubiquitously throughout the cell cycle whereas a smaller, alternate transcript (CDK11p58), the result of internal ribosomal entry, is expressed only during the G2/M transition where it promotes centrosome maturation and spindle formation (3-5). During induction of apoptosis by Fas or TNF, or anoikis, PITSLRE/CDK11 is cleaved by caspases to generate p110C, an approximately 46 kDa protein that contains the catalytically active kinase domain of PITSLRE/CDK11 that interacts with and inhibits p21-activated kinase (PAK1) activity (6-8). Full length PITSLRE/CDK11 (CDK11p110) appears to participate in pre-mRNA splicing events. This is demonstrated by the observation that CDK11p110 interacts with numerous splicing factors including RNPS1, 9G8/SRSF7 and cyclin L and that CDK11p110 can phosphorylate and inhibit the splicing activity of 9G8/SRSF7 (9-11).
