Secondary Information

Protein Function Meiotic proteins involved in Meiosis steps.Also involved in a signaling cascade leading to DSB repair in oocytes and spermatocytes.
Biochemical Properties The mouse and human genes share similar structure, both being comprised of nine exons encoding for proteins of 358 and 363 amino acids, respectively
Site(s) of PTM(s)

N-glycosylation, O-glycosylation,
Predicted Disorder Regions (1-203)
DisProt Annotation

Significance of PTMs Phosphorylation of SPATA22,there are also two putative ATR and ATM phosphorylation sites along the sequence of SPATA22. ATR is required for XY body formation and MSUC, and ATM is involved in signaling DSB repair following initiation of meiotic recombination
Additional Comments In spermatocytes of Spata22-deficient mutant rats, meiosis was arrested at the zygotene-like stage, and a normal number of Rpa foci was observed during leptotene- and zygotene-like stages.
