Western blot analysis of CPNE1 over-expressed 293 cell line, cotransfected with CPNE1 Validated Chimera RNAi ( Cat # H00008904-R01V ) (Lane 2) or non-transfected control (Lane 1). Blot probed with CPNE1 monoclonal antibody (M01), clone 8B8 (Cat # H00008904-M01 ). GAPDH ( 36.1 kDa ) used as specificity and loading control.
Calcium-dependent membrane-binding proteins may regulate molecular events at the interface of the cell membrane and cytoplasm. This gene encodes a calcium-dependent protein that also contains two N-terminal type II C2 domains and an integrin A domain-like sequence in the C-terminus. However, the encoded protein does not contain a predicted signal sequence or transmembrane domains. This protein has a broad tissue distribution and it may function in membrane trafficking. This gene and the gene for RNA binding motif protein 12 overlap at map location 20q11.21. Alternate splicing results in multiple transcript variants encoding different proteins. [provided by RefSeq
