[Term] id: PR:Q3LFS6 name: CEACAM1a-2C1 (mouse) def: "A carcinoembryonic antigen-related cell adhesion molecule 1 sequence variant CEACAM1a (mouse) that is a translation product of some mRNA whose exon structure and start site selection renders it capable of giving rise to a protein with the amino acid sequence represented by UniProtKB:Q3LFS6. This form contains the two copies of the Ig domain. This isoform lacks the transmembrane domain." [PRO:KRC, PMID:19358828, UniProtKB:P31809] comment: Category=organism-sequence. Evidence=(ECO:0000006, based on PMID:19358828, at mRNA and protein levels). Note: PMID:19358828 shows RT-PCR evidence of new isoforms for mRNA obtained from the small intestinal epithelium of BALB/c mice. Also shows presence of Ceacam1a-2C1 and/or -4C1 using protein using antibody specific to the frameshift sequence present in these two isoforms in the small intestine. synonym: "mCEACAM1a/iso:2C1" EXACT PRO-short-label [PRO:DAN] synonym: "CEACAM1(a)-2C1 (mouse)" EXACT [PMID:19358828] synonym: "Ceacam1a-2C1 (mouse)" EXACT [PMID:19358828] xref: UniProtKB:Q3LFS6 is_a: PR:000044466 ! carcinoembryonic antigen-related cell adhesion molecule 1 sequence variant CEACAM1a (mouse) relationship: only_in_taxon NCBITaxon:10090 !
