Species: Homo sapiens

Gene Type: protein coding

Gene ID: 124912

About SPACA3

Cytogenetic location: 17q11.2 Genomic coordinates (GRCh38): 17:32,991,847-32,997,877 (from NCBI)

This gene has 5 transcripts (splice variants), 121 orthologues and 8 paralogues. Restricted expression toward testis (RPKM 20.0).

Summary

The protein encoded by this gene is a sperm surface protein that may be involved in adhesion to the egg prior to fertilization. While the encoded protein has significant similarity to lysozyme at the amino acid level, it has no detectable bacteriocidal activity. Several transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Nov 2015]
