PRB4
Description
The PRB4 (proline rich protein BstNI subfamily 4) is a protein-coding gene located on chromosome 12.
The PRB4 gene, located on chromosome 12, encodes a protein known as basic salivary proline-rich protein 4. This protein is characterized by its high proline content and is a component of saliva. The PRB4 gene belongs to a cluster of six genes, all of which encode salivary proline-rich proteins, along with a gene encoding a similar protein found in the lacrimal gland. These genes are clustered together on chromosome 12 in the 12p13 region.
The PRB4 gene encodes a proline-rich protein found in saliva, contributing to the complex composition of salivary fluids.
PRB4 is also known as Po.
