About CPNE1

Cytogenetic location: 20q11.22 Genomic coordinates (GRCh38): 20:35,626,044-35,664,900 (from NCBI)

This gene has 28 transcripts (splice variants), 177 orthologues and 8 paralogues. Ubiquitous expression in spleen (RPKM 33.6), placenta (RPKM 33.3) and 25 other tissues.

Summary

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.
