60S ribosomal protein L9 is a
protein
Proteins are large biomolecules and macromolecules that comprise one or more long chains of amino acid residues. Proteins perform a vast array of functions within organisms, including catalysing metabolic reactions, DNA replication, res ...
that in humans is encoded by the ''RPL9''
gene
In biology, the word gene (from , ; "... Wilhelm Johannsen coined the word gene to describe the Mendelian units of heredity..." meaning ''generation'' or ''birth'' or ''gender'') can have several different meanings. The Mendelian gene is a b ...
.
s, 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
A ribosomal protein (r-protein or rProtein) is any of the proteins that, in conjunction with rRNA, make up the ribosomal subunits involved in the cellular process of translation. ''E. coli'', other bacteria and Archaea have a 30S small subunit an ...
that is a component of the 60S subunit. The protein belongs to the L6P family of ribosomal proteins. It is located in the
cytoplasm
In cell biology, the cytoplasm is all of the material within a eukaryotic cell, enclosed by the cell membrane, except for the cell nucleus. The material inside the nucleus and contained within the nuclear membrane is termed the nucleoplasm. ...
. As is typical for genes encoding ribosomal proteins, there are multiple processed
pseudogenes of this gene dispersed through the genome. Two
alternatively spliced
Alternative splicing, or alternative RNA splicing, or differential splicing, is an alternative splicing process during gene expression that allows a single gene to code for multiple proteins. In this process, particular exons of a gene may be ...
transcript variants encoding the same protein have been found for this gene.
