Summary: The protein encoded by this gene is similar to insulin in function and structure and is a member of a family of proteins involved in mediating growth and development. The encoded protein is processed from a precursor, bound by a specific receptor, and secreted. Defects in this gene are a cause of insulin-like growth factor I deficiency. Alternative splicing results in multiple transcript variants encoding different isoforms that may undergo similar processing to generate mature protein. [provided by RefSeq, Sep 2015]

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: REVIEWED

Description

Transcript Variant: This variant (4) lacks an alternate frame-shifting exon in the 3' coding region, compared to variant 1, resulting in a protein (isoform 4) with a novel C-terminus, compared to isoform 1. This isoform is also known as IA. Variants 4 and 7 both encode the same isoform (4).

Status: REVIEWED

Description

Transcript Variant: This variant (2) differs in the 5' UTR and has multiple coding region differences, compared to variant 1. These differences cause translation initiation from a distinct start codon and result in an isoform (2) with novel N- and C-termini, compared to isoform 1. This isoform is also known as IIA. This isoform (2) may undergo proteolytic processing similar to isoform 1.
