Anti-human CDCrel-1, FITC, (clone SP18), (Mouse IgG1)
DescriptionCDCrel-1/Septin 5 (Sept5) belongs to the Septin family of nucleotide binding GTPases. Septins were originally described in yeast as cell division cycle regulatory proteins involved in cytokinesis and the regulation of cytoskeletal organization. Sept5 is expressed in cells of the nervous system and is seen to associate primarily with vesicles and membranes through its interaction with the SNARE domain of syntaxin 1A. Through its interaction with syntaxin 1A Sept5 acts to inhibit exocytosis, possibly by regulating vesicle targeting and/or fusion. Recently it was shown that Sept5 is phosphorylated by cyclin-dependent kinase 5 (Cdk5) – p35 decreasing it’s binding to syntaxin 1A. This suggests that Cdk5 can modulate synaptic vesicle release by regulating the interactions between Sept5 and syntaxin 1A.______________________________________________________________________________________________________Immunofluorescence AnalysisPurified Anti-Human CDCrel-1/Septin 5 (CL2708AP) staining of paraformaldehyde-fixed paraffin-embedded human cerebellum sections at 400x magnification with DAPI counterstain.
