What's a GeneRIF?

These data demonstrate an essential role for CTC1 in promoting efficient replication and length maintenance of telomeres.
Title: CTC1 deletion results in defective telomere replication, leading to catastrophic telomere loss and stem cell exhaustion.

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.

See identical proteins and their annotated locations for NP_001268394.1

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.
