DescriptionRabbit polyclonal to CDKL5
SpecificitySwissprot predicts mouse CDKL5 protein to be ~105 kDa (Q3UTQ8), however a recent paper by Lin et al, 2006 (PMID: 16330482) indicated CDKL5 to run at ~118 kDa on WB. On this basis we think that the ~120 kDa band we observe using Rabbit polyclonal to CDKL5 (ab22453) on mouse tissue is CDKL5 specific. Futhermore the ~120 kDa band is blocked by the immunising peptide. The larger ~200 kDa is potentially also CDKL5 as a similar band is also observed in the Lin et al (2006) publication. There is evidence for larger forms of CDKL5 for the human version of the protein, so it may not be surprising to find a similar scenario for the mouse protein.

Our Abpromise guarantee covers the use of ab22453 in the following tested applications.
The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.
|WB||Use a concentration of 1 - 3 µg/ml. Detects a band of approximately 120,160 kDa (predicted molecular weight: 105 kDa).|
|IHC-P||1/800. Perform heat mediated antigen retrieval before commencing with IHC staining protocol.|
FunctionMediates phosphorylation of MECP2.
Tissue specificityExpressed in brain, lung, kidney, prostate, ovary, placenta, pancreas and testis.
Involvement in diseaseNote=Chromosomal aberrations involving CDKL5 are found in patients manifesting early-onset seizures and spams and psychomotor impairment. Translocation t(X;6)(p22.3;q14); translocation t(X;7)(p22.3;p15).
Defects in CDKL5 are a cause of epileptic encephalopathy early infantile type 2 (EIEE2) [MIM:300672]; also known as atypical CDKL5-related Rett syndrome. EIEE2 is a severe form of epilepsy characterized by seizures or spasms beginning in infancy. Patients manifest features resembling Rett syndrome such as microcephaly, lack of speech development, stereotypic hand movements.
Sequence similaritiesBelongs to the protein kinase superfamily. CMGC Ser/Thr protein kinase family. CDC2/CDKX subfamily.
Contains 1 protein kinase domain.

ab22453 staining nuclear CDKL5 in Human appendix. The paraffin embedded human skin tissue was incubated with ab22453 (1/800 dilution) for 30 mins at room temperature. Antigen retrieval was performed by heat induction in citrate buffer pH 6. Ab22453 was tested in a tissue microarray (TMA) containing a wide range of normal and cancer tissues as well as a cell microarray consisting of a range of commonly used, well characterised human cell lines.
