RPSA gene

The RPSA gene provides instructions for making a protein called ribosomal protein SA, which is one of approximately 80 different ribosomal proteins. These proteins come together to form 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 subunit and the small subunit. Ribosomal protein SA is part of the small subunit.

The specific roles of each of the ribosomal proteins within the ribosome are not entirely understood. 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. Research suggests that ribosomal protein SA helps the ribosome control the production of certain proteins, many of which are likely important for development before birth.
