60S ribosomal protein L23a
| View/Edit Human | |||
60S ribosomal protein L23a is a protein that in humans is encoded by the RPL23A gene.[2][3]
Function
Ribosomes, the organelles that catalyze protein synthesis, consist of a small 40S subunit and a large 60S subunit. Together these subunits are composed of 4 RNA species and approximately 80 structurally distinct proteins. This gene encodes a ribosomal protein that is a component of the 60S subunit. The protein belongs to the L23P family of ribosomal proteins. It is located in the cytoplasm. The protein may be one of the target molecules involved in mediating growth inhibition by interferon. In yeast, the corresponding protein binds to a specific site on the 26S rRNA. This gene is co-transcribed with the U42A, U42B, U101A, and U101B small nucleolar RNA genes, which are located in its third, first, second, and fourth introns, respectively. As is typical for genes encoding ribosomal proteins, there are multiple processed pseudogenes of this gene dispersed through the genome.[3]
Clinical significance
L23a has been identified as an autoimmune target that causes a form of rheumatoid arthritis in mice and which also causes a reaction from T cells and autoantibodies from human rheumatoid arthritis patients.[4]
