Biochem/physiol Actions

Four and a half LIM domains protein 1 is a protein encoded by the FHL1 gene in humans and is located on human chromosome Xq27.2. Factor IX (or Christmas factor) is one of the serine proteases of the coagulation system. It belongs to peptidase family S1 and its deficiency causes hemophilia B. The proteins belong to a novel family of LIM proteins that are expressed in human skeletal muscle. FHL1 gene is related to carcinogenesis and its inactivation is a frequent event during oral carcinogenesis. FHL1 downregulation in oral squamous cell carcinoma (OSCC) occurs through DNA methylation of the promoter region rather than histone deacetylation or mutation.
