Ready-to-use ELISA kits are available for the detection of HYPA, an alias of the protein, pre-mRNA processing factor 40 homolog A. The official gene symbol is PRPF40A. The protein, with a mass of 108.8 kDa and length of 957 residues, is reported to be nuclear. It is a member of the PRPF40 family and may be known by other names, including: formin-binding protein 11, formin binding protein 3, PRP40 pre-mRNA processing factor 40 homolog A, NY-REN-6 antigen, Huntingtin-interacting protein A, and Fas-ligand associated factor 1, and huntingtin-interacting protein 10.
