Summary: Sialic acid-binding immunoglobulin-like lectins (SIGLECs) are a family of cell surface proteins belonging to the immunoglobulin superfamily. They mediate protein-carbohydrate interactions by selectively binding to different sialic acid moieties present on glycolipids and glycoproteins. This gene encodes a member of the SIGLEC3-like subfamily of SIGLECs. Members of this subfamily are characterized by an extracellular V-set immunoglobulin-like domain followed by two C2-set immunoglobulin-like domains, and the cytoplasmic tyrosine-based motifs ITIM and SLAM-like. The encoded protein, upon tyrosine phosphorylation, has been shown to recruit the Src homology 2 domain-containing protein-tyrosine phosphatases SHP1 and SHP2. It has been suggested that the protein is involved in the negative regulation of macrophage signaling by functioning as an inhibitory receptor. This gene is located in a cluster with other SIGLEC3-like genes on 19q13.4. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Aug 2013]

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.

NM_001412258.1 → NP_001399187.1 sialic acid-binding Ig-like lectin 12 isoform c

Status: REVIEWED

Description

Transcript Variant: This variant (3) uses the same exon combination as variant 1 but represents the allele encoded by the T2T-CHM13v2.0 genome assembly. The encoded isoform (c) has a shorter and frameshifted N-terminus compared to isoform a.

Status: REVIEWED

Description

Transcript Variant: This variant (2), also known as SLG-Short (SLG-S), differs in the 5' UTR and uses an alternate segment in the 5' coding region compared to variant 1, resulting in the use of an alternate in-frame translation initiation codon. It encodes an isoform (b) with a different and shorter N-terminus compared to isoform a.

Status: REVIEWED

Description

Transcript Variant: This variant (1), also known as SLG-Long (SLG-L), encodes the longest isoform (a). Unlike other members of the SIGLEC3-like subfamily, which contain only one V-set immunoglobin-like domain, isoform a contains two. This variant uses the same exon combination as variant 3 but represents the allele encoded by the GRCh38 reference genome.
