Gene ID: 5359 | Gene type: protein coding

About PLSCR1

Cytogenetic location: 3q24 Genomic coordinates (GRCh38): 3:146,515,180-146,544,607 (from NCBI)

This gene has 19 transcripts (splice variants), 235 orthologues and 4 paralogues. Ubiquitous expression in appendix (RPKM 43.5), gall bladder (RPKM 33.7) and 25 other tissues.

Summary

This gene encodes a phospholipid scramblase family member. The encoded protein is involved in disruption of the asymmetrical distribution of Phospholipids between the inner and outer leaflets of the plasma membrane, resulting in externalization of phosphatidylserine. This cell membrane disruption plays an important role in the blood coagulation cascade as well as macrophage clearing of apoptotic cells. The encoded protein has additionally been implicated in gene regulation and interferon-induced Antiviral responses. [provided by RefSeq, May 2022]
