-   Size: 858 amino acids
-   Molecular mass: 94574 Da
-   Protein Accession: P13591
-   Family: May be produced at very low levels due to a premature stop codon in the mRNA, leading to nonsense-mediated mRNA decay
-   Domains: FN3_dom, FN3_sf, Ig-like_dom, Ig-like_dom_sf, Ig-like_fold, Ig_I-set, Ig_sub, Ig_sub2, Neural_cell_adh
-   NCAM1 and NCAM2 proteins have ectodomains with 5 Ig domains and 2 FnIII domains, with NCAM1's ATP binding to its Walker A motif interfering with FGFR binding, while NCAM2's FnIII domains form a rigid structure that binds and activates FGFR, inducing neurite outgrowth in a concentration-dependent manner through FGFR-dependent activation of the Ras-MAPK pathway [[PMID: 29895898]](https://www.ncbi.nlm.nih.gov/pubmed/29895898).
