RPL35A

Reviewed February 2012

What is the official name of the RPL35A gene?

The official name of this gene is “ribosomal protein L35a.”

RPL35A is the gene's official symbol. The RPL35A gene is also known by other names, listed below.

What is the normal function of the RPL35A gene?

The RPL35A 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 RPL35A gene is among those found in the large subunit.

The specific functions of the RPL35A 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 RPL35A gene share characteristics with other genes?

The RPL35A gene belongs to a family of genes called RPL (L 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? (http://ghr.nlm.nih.gov/handbook/howgeneswork/genefamilies) in the Handbook.

How are changes in the RPL35A gene related to health conditions?

Diamond-Blackfan anemia - caused by mutations in the RPL35A gene

At least five RPL35A gene mutations have been identified in individuals with Diamond-Blackfan anemia. These mutations are believed to affect the stability or function of the RPL35A protein. Studies indicate that a shortage of functioning ribosomal proteins may increase the self-destruction of blood-forming cells in the bone marrow, resulting in a low number of red blood cells (anemia). Abnormal regulation of cell division or inappropriate triggering of apoptosis may contribute to the other health problems and unusual physical features that affect some people with Diamond-Blackfan anemia.

Where is the RPL35A gene located?

Cytogenetic Location: 3q29

Molecular Location on chromosome 3: base pairs 197,950,134 to 197,955,850

The RPL35A gene is located on the long (q) arm of chromosome 3 at position 29.

The RPL35A gene is located on the long (q) arm of chromosome 3 at position 29.

More precisely, the RPL35A gene is located from base pair 197,950,134 to base pair 197,955,850 on chromosome 3.
