Summary: Enables RNA binding activity and single-stranded DNA binding activity. Predicted to be involved in double-strand break repair via homologous recombination; mitotic G2/M transition checkpoint; and response to ionizing radiation. Located in chromosome, telomeric region and nucleus. Is expressed in several structures, including genitourinary system; heart; liver; lung; and spleen. Orthologous to human NABP1 (nucleic acid binding protein 1). [provided by Alliance of Genome Resources, Nov 2024]

Ssb1 is likely able to compensate for the loss of Ssb2 in mice.
Title: Ssb2/Nabp1 is dispensable for thymic maturation, male fertility, and DNA repair in mice.
NABP1 binds single-stranded nucleic acids, but not double-stranded DNA, suggesting that it functions as a single-stranded nucleic acid binding protein

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.

mRNA and Protein(s)

NM_001310548.1 → NP_001297477.1 SOSS complex subunit B2 isoform b

Status: VALIDATED

Description

Transcript Variant: This variant (2) uses an alternate splice junction in the 5' end compared to variant 1, which results in translation from a downstream AUG. The resulting isoform (b) is shorter at the N-terminus compared to isoform a. Variants 2 and 3 both encode the same isoform (b).
