Insulin-like growth factor 1 receptor

Gene

igf1r

Organism
Xenopus laevis (African clawed frog)
Status
Reviewed-Annotation score: Annotation score: 5 out of 5-Experimental evidence at protein leveli

Functioni

This receptor binds insulin-like growth factor 1 (IGF1) with a high affinity and IGF2 with a lower affinity. It has a tyrosine-protein kinase activity, which is necessary for the activation of the IGF1-stimulated downstream signaling cascade. Plays a role in oocyte maturation. Promotes head development by inhibiting Wnt signaling during embryogenesis.3 Publications

Post-translational modificationi

The cytoplasmic domain of the beta subunit is autophosphorylated on Tyr residues in response to low concentrations of insulin-like growth factor (IGF 1) and higher concentrations of insulin.

Expressioni

Developmental stagei

Expressed both maternally and zygotically. Shows biphasic expression during early development. Expressed ubiquitously in fertilized eggs and throughout the midblastula transition. Expression then decreases at mid-gastrulation. Shortly after gastrulation, expression is seen throughout the dorsal side of the embryo with expression strongest in the anterior and absent ventrally. Expression increases along the dorsal midline at early neurulation and is seen in the head region as neurulation progresses, particularly in the area of the cement gland primordium. Also present in the anterior mesoderm but is absent from the neural tube and the most ventral part of the embryo. Remains expressed throughout early embryogenesis. By the tailbud stages, expression is anterior, in the head and the most rostral part of the neural tube.3 Publications

Interactioni

Subunit structurei

Tetramer of 2 alpha and 2 beta chains linked by disulfide bonds. The alpha chains contribute to the formation of the ligand-binding domain, while the beta chain carries the kinase domain (By similarity).By similarity

Links to similar proteins from the UniProt Reference Clusters (UniRef) at 100%, 90% and 50% sequence identity:
100%UniRef100 combines identical sequences and sub-fragments with 11 or more residues from any organism into one UniRef entry.
90%UniRef90 is built by clustering UniRef100 sequences that have at least 90% sequence identity to, and 80% overlap with, the longest sequence (a.k.a seed sequence).
50%UniRef50 is built by clustering UniRef90 seed sequences that have at least 50% sequence identity to, and 80% overlap with, the longest sequence in the cluster.
