Anti-Cus1 antibodies enable researchers to detect and measure the Cus1 antigen in biological samples. This target is a reported synonym of the SF3B2 gene, which encodes splicing factor 3b subunit 2. This protein is known to function in mRNA processing and RNA splicing, among other biological roles. The human version of Cus1 has a canonical amino acid length of 895 residues and a protein mass of 100.2 kilodaltons. It is reported to be localized in the nucleus of cells and widely expressed in many tissue types. Other names for this target antigen include CFM and HFM. Indicated applications for Cus1 antibodies listed below include ELISA, Western Blot, Immunofluorescence, and Immunohistochemistry.
