Gene: IGSF21 (immunoglobin superfamily member 21) Homo sapiens
Symbol: IGSF21
Name: immunoglobin superfamily member 21
Description: Predicted to have cell adhesion molecule binding activity; protein homodimerization activity; and signaling receptor activity. Predicted to be involved in heterophilic cell-cell adhesion via plasma membrane cell adhesion molecules; homophilic cell adhesion via plasma membrane adhesion molecules; and synapse maturation. Predicted to localize to several cellular components, including adherens junction; anchored component of external side of plasma membrane; and inhibitory synapse.
Type: protein-coding
RefSeq Status: REVIEWED
