Also known as TMG3
Summary
PRRG3 (proline rich and Gla domain 3, HGNC:30798) is a protein-coding gene on chromosome Xq28, encoding Transmembrane gamma-carboxyglutamic acid protein 3 (Q9BZD7).
This gene encodes a protein which contains a vitamin K-dependent carboxylation/gamma-carboxyglutamic domain. The encoded protein is a member of a family of vitamin K-dependent transmembrane proteins which contain a glutamate-rich extracellular domain.
