Gene: Spag1 (sperm associated antigen 1) Mus musculus
Symbol: Spag1
Name: sperm associated antigen 1
Description: Predicted to have GTP binding activity and hydrolase activity. Predicted to be involved in single fertilization. Predicted to localize to the cytosol. Human ortholog(s) of this gene implicated in primary ciliary dyskinesia 28. Orthologous to human SPAG1 (sperm associated antigen 1); INTERACTS WITH 2,3,7,8-tetrachlorodibenzodioxine; aflatoxin B1; choline.
Type: protein-coding
RefSeq Status: VALIDATED
Also known as: infertility-related sperm protein Spag-1; sperm-associated antigen 1; tpis; TPR-containing protein involved in spermatogenesis
