What is the official name of the PLCB4 gene?The official name of this gene is “phospholipase C, beta 4.” PLCB4 is the gene's official symbol. The PLCB4 gene is also known by other names, listed below. Read more about gene names and symbols on the About page. What is the normal function of the PLCB4 gene?The PLCB4 gene provides instructions for making one form (the beta 4 isoform) of a protein called phospholipase C. This protein is involved in a signaling pathway within cells known as the phosphoinositide cycle, which helps transmit information from outside the cell to inside the cell. Phospholipase C carries out one particular step in the phosphoinositide cycle: the conversion of a molecule called phosphatidylinositol 4,5-bisphosphate (PIP2) to two smaller molecules, inositol 1,4,5-trisphosphate (IP3) and 1,2-diacylglycerol. These smaller molecules relay messages into the cell that ultimately influence many cell activities. Studies suggest that the beta 4 isoform of phospholipase C contributes to the development of the first and second pharyngeal arches. These embryonic structures ultimately develop into the jawbones, facial muscles, middle ear bones, ear canals, outer ears, and related tissues. This protein is also thought to play a role in vision, particularly in the function of the retina, which is a specialized tissue at the back of the eye that detects light and color.

Where is the PLCB4 gene located?Cytogenetic Location: 20p12 Molecular Location on chromosome 20: base pairs 9,049,700 to 9,461,462 The PLCB4 gene is located on the short (p) arm of chromosome 20 at position 12. More precisely, the PLCB4 gene is located from base pair 9,049,700 to base pair 9,461,462 on chromosome 20. See How do geneticists indicate the location of a gene? in the Handbook.
