Protein Structure
|
|
Function |
Single-stranded DNA-binding protein required for homologous recombination in meiosis I. Required for double strand breaks (DSBs) repair and crossover formation and promotion of faithful and complete synapsis. Not required for the initial loading of recombinases but required to maintain a proper number of RAD51 and DMC1 foci after the zygotene stage. May act by ensuring the stabilization of recombinases, which is required for successful homology search and meiotic recombination. Displays Single-stranded DNA 3'-5' exonuclease activity in vitro (By similarity). {ECO:0000250}.
|
Subcellular Localization |
Cytoplasm {ECO:0000250}. Nucleus {ECO:0000250}. Chromosome {ECO:0000250}. Note=Co-localizes with the RPA complex on meiotic chromosome axes. Accumulates on resected DNA. Localization is dependent on SPATA22 (By similarity). {ECO:0000250}.

Disease Associations |
|
Tissue Specificity |
In fetal gonads, specifically expressed in the ovary starting at the 14th weeks post fertilization. {ECO:0000269PubMed:24068956}.
