About DDX3Y

Cytogenetic location: Yq11.221 Genomic coordinates (GRCh38): Y:12,903,999-12,920,478 (from NCBI)

This gene has 9 transcripts (splice variants), 221 orthologues, 38 paralogues and is associated with 1 phenotype. Broad expression in bone marrow (RPKM 32.5), testis (RPKM 29.4) and 19 other tissues.

Summary

The protein encoded by this gene is a member of the DEAD-box RNA helicase family, characterized by nine conserved motifs, included the conserved Asp-Glu-Ala-Asp (DEAD) motif. These motifs are thought to be involved in ATP binding, hydrolysis, RNA binding, and in the formation of intramolecular interactions. This protein shares high similarity to DDX3X, on the X chromosome, but a deletion of this gene is not complemented by DDX3X. Mutations in this gene result in male infertility, a reduction in germ cell numbers, and can result in Sertoli-cell only sydrome. Pseudogenes sharing similarity to both this gene and the DDX3X paralog are found on chromosome 4 and the X chromosome. Alternative splicing results in multiple transcript variants encoding different isoforms. [provided by RefSeq, Oct 2014]
