What is the official name of the MT-TS1 gene?
The official name of this gene is “mitochondrially encoded tRNA serine 1 (UCN).”
MT-TS1 is the gene's official symbol. The MT-TS1 gene is also known by other names, listed below.

What is the normal function of the MT-TS1 gene?
The MT-TS1 gene provides instructions for making a particular type of RNA, a molecule that is a chemical cousin of DNA. This type of RNA, called transfer RNA (tRNA), helps assemble protein building blocks known as amino acids into full-length, functioning proteins. The MT-TS1 gene provides instructions for a specific form of tRNA that is designated as tRNASer(UCN). During protein assembly, this molecule attaches to a particular amino acid, serine (Ser), and inserts it into the appropriate locations in the growing protein.
The tRNASer(UCN) molecule is present in cellular structures called mitochondria. These structures convert energy from food into a form that cells can use. Through a process called oxidative phosphorylation, mitochondria use oxygen, simple sugars, and fatty acids to create adenosine triphosphate (ATP), the cell's main energy source. The tRNASer(UCN) molecule is involved in the assembly of proteins that carry out oxidative phosphorylation.
Does the MT-TS1 gene share characteristics with other genes?
The MT-TS1 gene belongs to a family of genes called TRNA (transfer RNAs).
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? in the Handbook.
