Anti-MSL1v1 antibodies enable researchers to detect and measure the MSL1v1 antigen in biological samples. This target is a reported synonym of the KANSL1 gene, which encodes KAT8 regulatory NSL complex subunit 1. This protein is known to function in chromatin organization and the regulation of transcription, among other biological roles. The human version of MSL1v1 has a canonical amino acid length of 1105 residues and a protein mass of 121 kilodaltons, although 3 isoforms have been identified. It is reported to be localized in the nucleus of cells and notably expressed in many tissues, such as the breast, vagina, and adrenal gland.
