What is the official name of the RPS19 gene?
The official name of this gene is “ribosomal protein S19.”
RPS19 is the gene's official symbol. The RPS19 gene is also known by other names, listed below.

What is the normal function of the RPS19 gene?
The RPS19 gene provides instructions for making one of approximately 80 different ribosomal proteins, which are components of cellular structures called ribosomes. Ribosomes process the cell's genetic instructions to create proteins.
Each ribosome is made up of two parts (subunits) called the large and small subunits. The protein produced from the RPS19 gene is among those found in the small subunit.
The specific functions of the RPS19 protein and the other ribosomal proteins within these subunits are unclear. Some ribosomal proteins are involved in the assembly or stability of ribosomes. Others help carry out the ribosome's main function of building new proteins. Studies suggest that some ribosomal proteins may have other functions, such as participating in chemical signaling pathways within the cell, regulating cell division, and controlling the self-destruction of cells (apoptosis).
Does the RPS19 gene share characteristics with other genes?
The RPS19 gene belongs to a family of genes called RPS (S ribosomal proteins).
A gene family is a group of genes that share important characteristics. Classifying individual genes into families helps researchers describe how genes are related to each other. For more information, see What are gene families? in the Handbook.
