Summary: Predicted to enable protein kinase activator activity and signaling receptor binding activity. Involved in several processes, including cellular response to mechanical stimulus; positive regulation of blood vessel endothelial cell migration; and positive regulation of vascular endothelial cell proliferation. Located in extracellular space. Used to study osteoporosis. Biomarker of several diseases, including alcoholic neuropathy; brain infarction; congenital diaphragmatic hernia; diabetes mellitus (multiple); and hepatocellular carcinoma. Human ortholog(s) of this gene implicated in Silver-Russell syndrome; choriocarcinoma; hepatocellular carcinoma; and rheumatoid arthritis. Orthologous to human IGF2 (insulin like growth factor 2).

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_001177091.1

Status: VALIDATED

Description

Transcript Variant: This variant (2) uses an alternate exon at its 5' terminus and uses a downstream in-frame start codon, compared to variant 1. This results in a protein (isoform 2) with a shorter N-terminus, compared to isoform 1. Variants 2 and 3 encode the same protein.
