Mouse anti FOXP1 antibody, clone JC12 recognizes human FOXP1, also known as Forkhead box protein P1, Mac-1-regulated forkhead or MFH. FOXP1 is a 677 amino acid~85 kDa transcriptional repressor and member of the winged helix/forkhead transcription factor family. The FOXP1 transcription factor is widely expressed in human tissues and is predominantly localised to the nucleus. However, the level of expression does vary between cells and between different tissues. The expression of FOXP1 is reported to be abnormal in a range of solid tumours (Giatromanolaki et al. 2006).

Mouse anti FOXP1 antibody, clone JC12 does not recognize closely related molecules FOXP2, FOXP3 or FOXP4.

Mouse anti FOXP1 antibody, clone JC12 was derived from a fusion intended to isolate antibodies against human Bcl-X. However the JC12 clone did not bind to the immunogen and was considered to be from a B cell secreting an autoantibody expanded during the fusion process. Sequencing of the bound target indicated that the clone JC12 recognizes both human and murine FOXP1 (Banham et al. 2001).
