Gene

SPAG1

Species
Homo sapiens
Symbol
SPAG1
Name
sperm associated antigen 1
Synonyms
  • CILD28
  • CT140
Biotype
protein coding gene
Automated Description
Predicted to enable GTP binding activity and hydrolase activity. Predicted to be involved in axonemal dynein complex assembly. Located in cytosol. Part of protein folding chaperone complex. Implicated in primary ciliary dyskinesia 28.
RGD Description
The correlation of anti-sperm antibodies with cases of unexplained infertility implicates a role for these antibodies in blocking fertilization. Improved diagnosis and treatment of immunologic infertility, as well as identification of proteins for targeted contraception, are dependent on the identification and characterization of relevant sperm antigens. The protein expressed by this gene is recognized by anti-sperm agglutinating antibodies from an infertile woman. Furthermore, immunization of female rats with the recombinant human protein reduced fertility. This protein localizes to the plasma membrane of germ cells in the testis and to the post-acrosomal plasma membrane of mature spermatozoa. Recombinant polypeptide binds GTP and exhibits GTPase activity. Thus, this protein may regulate GTP signal transduction pathways involved in spermatogenesis and fertilization. Two transcript variants of this gene encode the same protein. [provided by RefSeq, Jul 2008]
