Anti-PPEF1 Antibody Picoband®

Serine/threonine-protein phosphatase with EF-hands 1 is an enzyme that in humans is encoded by the PPEF1 gene. This gene encodes a member of the serine/threonine protein phosphatase with EF-hand motif family. The protein contains a protein phosphatase catalytic domain, and at least two EF-hand calcium-binding motifs in its C terminus. Although its substrate (s) is unknown, the encoded protein has been suggested to play a role in specific sensory neuron function and/or development. This gene shares high sequence similarity with the Drosophila retinal degeneration C (rdgC) gene. Several alternatively spliced transcript variants, each encoding a distinct isoform, have been described.

E.coli-derived human PPEF1 recombinant protein (Position: H137-L652) . Human PPEF1 shares 72.7% and 73.2% amino acid (aa) sequence identity with mouse and rat PPEF1, respectively.
