Rabbit anti-Human SSBP1 Polyclonal Antibody

Uniprot Id

Q04837

Target Species

Human

Target Name

SSBP1

Target Full Name

Single-stranded DNA-binding protein, mitochondrial

Target Function

Binds preferentially and cooperatively to pyrimidine rich single-stranded DNA (ss-DNA). In vitro, required to maintain the copy number of mitochondrial DNA (mtDNA) and plays a crucial role during mtDNA replication by stimulating the activity of the replisome components POLG and TWNK at the replication fork. Promotes the activity of the gamma complex polymerase POLG, largely by organizing the template DNA and eliminating secondary structures to favor ss-DNA conformations that facilitate POLG activity. In addition it is able to promote the 5'-3' unwinding activity of the mtDNA helicase TWNK. May also function in mtDNA repair.

Target Subcellular Location

Mitochondrion. Mitochondrion matrix, mitochondrion nucleoid.

Target Tissue Specificity

Expressed in retinal ganglion cells, photoreceptors, pigmented epithelium and fibroblasts (at protein level).

Target Background

SSBP1 is a housekeeping gene involved in mitochondrial biogenesis (Tiranti et al., 1995 [PubMed 7789991]). It is also a subunit of a single-stranded DNA (ssDNA)-binding complex involved in the maintenance of genome stability (Huang et al., 2009) [PubMed 19683501].
