DPY19L2 explained
Dpy-19-like 2 (C. elegans) is a protein that in humans is encoded by the DPY19L2 gene.[1]
Function
The C. elegans gene dpy-19 belongs to the dpy ("dumpy" phenotype)[2] gene class and encodes DPY-19, transmembrane protein with C-linked mannosyltransferase activity.[3] [4] In humans, it is highly expressed in testis, and is required for sperm head elongation and acrosome formation during spermatogenesis. Mutations in this gene are associated with an infertility disorder, spermatogenic failure type 9 (SPGF9).
