The function of ENSG00000129933 (MAU2, MAU2 sister chromatid cohesion factor) is as follows. Plays an important role in the loading of the cohesin complex on to DNA. Forms a heterodimeric complex (also known as cohesin loading complex) with NIPBL/SCC2 which mediates the loading of the cohesin complex onto chromatin (PubMed:22628566, PubMed:28167679). Plays a role in sister chromatid cohesion and normal progression through prometaphase (PubMed:16682347, PubMed:16802858). {ECO:0000269|PubMed:16682347, ECO:0000269|PubMed:16802858, ECO:0000269|PubMed:22628566, ECO:0000269|PubMed:28167679}.
