Protein

• UniProt ID: Q8IUH8
• Protein name: Signal peptide peptidase-like 2C (SPP-like 2C) (SPPL2c) (EC 3.4.23.-) (Intramembrane protease 5) (IMP-5)
• Protein function: Sperm-specific intramembrane-cleaving aspartic protease (I-CLiP) that cleaves distinct tail-anchored proteins and SNARE proteins (PubMed:30733281). In elongated spermatids, modulates intracellular Ca(2+) homeostasis by controlling PLN abundance
