Gene type: protein coding
RefSeq status: REVIEWED
Organism: Homo sapiens
Lineage: Eukaryota; Metazoa; Chordata; Craniata; Vertebrata; Euteleostomi; Mammalia; Eutheria; Euarchontoglires; Primates; Haplorrhini; Catarrhini; Hominidae; Homo
Also known as: SPRR1; GADD33; SPR-IB; CORNIFIN
Summary: The protein encoded by this gene is an envelope protein of keratinocytes. The encoded protein is crosslinked to membrane proteins by transglutaminase, forming an insoluble layer under the plasma membrane. This protein is proline-rich and contains several tandem amino acid repeats. [provided by RefSeq, Nov 2015]

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.
