Also known as FLJ32934
Summary
DCST2 (DC-STAMP domain containing 2, HGNC:26562) is a protein-coding gene on chromosome 1q21.3, encoding DC-STAMP domain-containing protein 2 (Q5T1A1). Essential sperm cell-surface protein required for sperm-egg fusion and fertilization.
Predicted to be involved in fusion of sperm to egg plasma membrane involved in single fertilization and sperm-egg recognition. Predicted to be located in acrosomal membrane.

Literature-anchored findings (GeneRIF, showing 2)
- OS9 is critically involved in the modulation of ER-to-Golgi transport of DC-STAMP in response to TLR triggering, suggesting a novel role for OS9 in myeloid differentiation and cell fusion. (PMID:18952287)
- This study highlights that common variation in DCST2 influences variation in early growth and adult height. (PMID:25281659)
