SIGLEC12 is a single-pass type I transmembrane protein belonging to the sialic acid binding Ig-like lectin (SIGLEC) family in the immunoglobulin superfamily (IgSF). SIGLECs are characterized by an N-terminal Ig-like V-type (IgV)domain that mediates sialic acid binding, followed by varying numbers (2 to 17) of Ig-like C2-type (IgC2) domains in the extracellular region, a transmembrane region, and a cytoplasmic tail with intracellular immunoreceptor tyrosine-based inhibitory motifs (ITIM). They can be classified into two subgroups: Siglecs-1, -2, and -4 subgroup, and a Siglec-3/CD33-related subgroup (Siglecs-3, and -5 through -13), defined by sequence similarity and clustered gene localization. SIGLECs are widely expressed on hematopoietic cells, often in a cell-type-specific manner.  Unlike other family members, SIGLEC12 contains 2 IgV and 2 IgC2 domains and may act as an adhesion molecule that mediates sialic-acid dependent binding to cells. In the immune response, SIGLEC12 may act as an inhibitory receptor upon ligand induced tyrosine phosphorylation by recruiting cytoplasmic phosphatases via their SH2 domains that block signal transduction through dephosphorylation of signaling molecules.

Primers: Gene insert coding sequence can be confirmed by following primers:

(a) forward (or 5'-end) primer: 5’-CAAATGGGCGGTAGGCGTG-3’;

(b) reverse (or 3'-end) primer: 5’-CCAGGTTTCCGGGCCCTCAC-3’

 

 

Note: The sequence may vary due to the naturally occurring variants or mutations, such as single nucleotide polymorphism, or the artifact during PCR amplification.  High fidelity PCR systems should always be used.
