Surfeit is a human

gene cluster A gene family is a set of homologous genes within one organism. A gene cluster is a group of two or more genes found within an organism's DNA that encode similar polypeptides, or proteins, which collectively share a generalized function and are ...

chromosome 9 Chromosome 9 is one of the 23 pairs of chromosomes in humans. Humans normally have two copies of this chromosome, as they normally do with all chromosomes. Chromosome 9 spans about 138 million base pairs of nucleic acids (the building blocks of D ...

that do not share sequence similarity. Genes in this cluster are numbered 1 through 6:

SURF1 Surfeit locus protein 1 (SURF1) is a protein that in humans is encoded by the ''SURF1'' gene. The protein encoded by ''SURF1'' is a component of the mitochondrial translation regulation assembly intermediate of cytochrome c oxidase complex (MITRAC ...

SURF2 SURF2 is a protein which in humans is encoded by the ''SURF2'' 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 ''ge ...

SURF3 60S ribosomal protein L7a is a protein that in humans is encoded by the ''RPL7A'' gene. Cytoplasmic ribosomes, organelles that catalyze protein synthesis, consist of a small 40S subunit and a large 60S subunit. Together these subunits are co ...
