Rabbit anti-Human POLRMT Polyclonal Antibody

Uniprot Id

O00411

Target Species

Human

Target Name

POLRMT

Target Full Name

DNA-directed RNA polymerase, mitochondrial

Target Function

DNA-dependent RNA polymerase catalyzes the transcription of mitochondrial DNA into RNA using the four ribonucleoside triphosphates as substrates. Component of the mitochondrial transcription initiation complex, composed at least of TFB2M, TFAM and POLRMT that is required for basal transcription of mitochondrial DNA. In this complex, TFAM recruits POLRMT to a specific promoter whereas TFB2M induces structural changes in POLRMT to enable promoter opening and trapping of the DNA non-template strand.

Target Subcellular Location

Mitochondrion.

Target Protein Families

Phage and mitochondrial RNA polymerase family

Target Synonyms

APOLMT; DNA-directed RNA polymerase; DNA-directed RNA polymerase mitochondrial; h-mtRPOL; mitochondrial; MTRNAP; MtRPOL; POLRMT; polymerase (RNA) mitochondrial (DNA directed); polymerase, RNA, mitochondrial; RPOM; RPOM_HUMAN

Target Background

This gene encodes a mitochondrial DNA-directed RNA polymerase. The gene product is responsible for mitochondrial gene expression as well as for providing RNA primers for initiation of replication of the mitochondrial genome. Although this polypeptide has the same function as the three nuclear DNA-directed RNA polymerases, it is more closely related to RNA polymerases of phage and mitochondrial polymerases of lower eukaryotes.
