Summary: Enables sodium channel regulator activity. Involved in transepithelial transport. Acts upstream of or within hair follicle development and positive regulation of sodium ion transport. Located in external side of plasma membrane and membrane raft. Is expressed in several structures, including alimentary system; brain; extraembryonic component; genitourinary system; and sensory organ. Used to study autosomal recessive congenital ichthyosis 4B and congenital secretory sodium diarrhea 3. Orthologous to human PRSS8 (serine protease 8).

Genetic Prss8 deficiency caused colitis and an inflamed rectum at an early age and intestinal tumors at a late age, with increased intestinal cell proliferation and migration but decreased cell differentiation. Increased PRSS8 inhibited cancer growth and metastasis in nude mice and inhibited cancer cell migration, invasion, colony and tumor sphere formation.PRSS8 targeted Wnt/beta-catenin, stem-cell, and EMT signaling.

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
