What pLDDT means and how to read it

Function

Involved in sister chromatid cohesion (PubMed:10882066). Forms a complex with SCC2, which is required for the association of the cohesin complex with chromosomes (PubMed:10882066, PubMed:26038942). Binds to the nucleosome-free promoter regions of ribosomal protein genes and tRNA genes (PubMed:25173104)

Subunit structure

Interacts with SCC2 to form the cohesin loading complex
