Summary: Enables 6-phosphofructo-2-kinase activity and fructose-2,6-bisphosphate 2-phosphatase activity. Predicted to be involved in several processes, including fructose 2,6-bisphosphate metabolic process; monocarboxylic acid metabolic process; and positive regulation of insulin secretion. Predicted to be located in nucleoplasm. Predicted to be active in cytosol. Is expressed in several structures, including alimentary system; genitourinary system; integumental system; nervous system; and respiratory system.

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.

RNA

NR_027859.1 RNA Sequence

Status: VALIDATED

Description

Transcript Variant: This variant (4) uses a distinct 3' splice pattern, compared to variant 1. This variant is represented as non-coding because the use of the 5'-most expected translational start codon, as used in variant 1, renders the transcript a candidate for nonsense-mediated mRNA decay (NMD).
