On the other hand, how or regardless of whether phosphorylation obviously of these tyrosines occurs and prospects to downstream signaling has but to get analyzed.7. CLEC-2CLEC-2 continues to be identified together with CLEC-1 in human myeloid cells [16, 82], and similar to CLEC-1, the only other species the place CLEC-2 continues to be characterized up to now is rodents . Predicted sequences derived from automated computational analysis of sequences with large homology on the human and rodent proteins are available for canine and bovine CLEC-2 with 70% and 69% protein identity for the human receptor, respectively. Interestingly, CLEC-2 won't seem to be as really conserved as CLEC-1 as even the conservation in between human and also the predicted chimpanzee CLEC-2 is only 96.9% as in comparison with 99.3% identity concerning human and chimpanzee CLEC-1.
As outlined before, opossums have a minimal NK gene complicated containing putative orthologs of CLEC-1 and CLEC-2 [33, 85]. Available sequences have only the area encoding the CTLD, and alignment of these citation to the human CLEC-2 sequence success within a similarity of 74% (Table two).CLEC-2 is observed to bind on the exogenous ligand rhodocytin, a snake venom,  along with the endogenous ligand podoplanin, a protein expressed on lymphatic but not vascular endothelium . Human CLEC-2 has 1 YXXL motif in its cytoplasmic tail which undergoes tyrosine phosphorylation by Src kinases on ligand binding . Binding of podoplanin by CLEC-2 expressed on platelets leads to platelet activation and continues to be implicated in tumor metastasis and lymphatic/blood vessel separation throughout advancement.
Additionally, it may additionally perform a role in HIV transmission [91�C93]. In mice, CLEC-2 continues to be shown to get expressed on neutrophils, in which it mediates phagocytosis and proinflammatory cytokine manufacturing . In this examine, phagocytosis is investigated applying antibody-coated Interleukin-9 receptor beads, however the pathogens acknowledged and taken up by CLEC-2, even now need to be identified. However, these outcomes indicate that CLEC-2, like LOX-1 and DECTIN-1, could have innate immune pattern recognition function.In contrast to people which only express the full-length CLEC-2, mice seem to have two more splice variants. mCLEC-2b lacks the transmembrane region, and more deletions in mCLEC-2c cause a frameshift leading to a truncated protein. As these isoforms present diverse expression patterns and subcellular localization, they could serve distinctive and possibly even regulatory functions .
