| Subcellular Location | Secreted |
| Developmental Stage | Expressed predominantly in fetal tissues and at lower levels in adult. |
| Similarity | Belongs to the insulin family. |
| Tissue Specificity | NA |
| Post Translational Modification | Proteolytically processed by PCSK4; proIGF2 is cleaved at Arg-128 and Arg-92 to generate big-IGF2 and mature IGF2. |
| Function | The insulin-like growth factors possess growth-promoting activity. Major fetal growth hormone in mammals. Plays a key role in regulating fetoplacental development. IGF2 is influenced by placental lactogen. Also involved in tissue differentiation. In adults; involved in glucose metabolism in adipose tissue; skeletal muscle and liver. Acts as a ligand for integrin which is required for IGF2 signaling. Positively regulates myogenic transcription factor MYOD1 function by facilitating the recruitment of transcriptional coactivators; thereby controlling muscle terminal differentiation. Inhibits myoblast differentiation and metabolism via increasing the mitochondrial respiration rate. |
