Protein

High affinity immunoglobulin epsilon receptor subunit gamma

Gene

Fcer1g

Organism
Rattus norvegicus (Rat)
Status
Reviewed-Annotation score: Annotation score: 5 out of 5-Experimental evidence at protein leveli

Functioni

Associates with a variety of FcR alpha chains to form a functional signaling complex. Regulates several aspects of the immune response. The gamma subunit has a critical role in allowing the IgE Fc receptor to reach the cell surface. Also involved in collagen-mediated platelet activation and in neutrophil activation mediated by integrin (By similarity).By similarity

Interactioni

Subunit structurei

IgE Fc receptor is a tetramer of an alpha chain, a beta chain, and two disulfide linked gamma chains. The gamma chain from Fc-epsilon-Ri are also subunits of other Fc receptors like FCGR1A (By similarity). Associated with CLEC6A (By similarity). Interacts with CLEC4E (By similarity). Interacts (via ITAM domain) with SYK (via SH2 domains); activates SYK, enabling integrin-mediated activation of neutrophils and macrophages (By similarity). Interacts with CD300LH; the interaction may be indirect (By similarity). Interacts with CD300LD (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.
