SRSF1 regulates lung cancer cell radioresistance through modulating PTPMT1 splicing. Reduced SRSF1 favors the production of short isoforms of PTPMT1 upon ionizing radiation, which in turn promotes phosphorylation of AMPK, thereby inducing DNA double-strand break to sensitize cancer cells to irradiation.

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.

See identical proteins and their annotated locations for NP_001137456.1

Status: VALIDATED

Description

Transcript Variant: This variant (2)reads through an intron and omits an exon, compared to variant 1. This results in a frameshift and a predicted protein with a distinct C-terminus (isoform 2).
