Summary
Enables single-stranded DNA binding activity. Involved in positive regulation of DNA replication. Acts upstream of or within several processes, including hematopoietic or lymphoid organ development; replicative senescence; and telomere maintenance via telomere lengthening. Located in chromosome, telomeric region and nucleus. Part of CST complex. Is expressed in genitourinary system; mesonephric tubule; mesonephros; and nephric duct, metanephric portion. Orthologous to human CTC1 (CST telomere replication complex component 1). [provided by Alliance of Genome Resources, Apr 2022]

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.

    Status: VALIDATED

    Description
    Transcript Variant: This variant (4) has multiple differences, compared to variant 1. These differences result in a distinct 5' UTR and cause translation initiation at a downstream start codon, compared to variant 1. The encoded protein (isoform d) is shorter than isoform a.

    Status: VALIDATED

    Description
    Transcript Variant: This variant (2) has multiple differences, compared to variant 1. This variant represents translation initiation at a downstream AUG compared to variant 1; the 5'-most initiation codon, as used in variant 1, is associated with a truncated ORF that would render the transcript a candidate for nonsense-mediated decay (NMD). Leaky scanning may allow translation initiation at the downstream AUG. The encoded protein (isoform b) is shorter than isoform a.
