Facts about Megakaryocyte and platelet inhibitory receptor G6b.
This regulation of megakaryocate function in addition to platelet production ann activation is done through the inhibition (through the 2 ITIM motifs) of the receptors CLEC1B and GP6:FcRgamma signaling (PubMed:17311996). Appears to function in a calcium-independent manner (PubMed:12665801).

Expressed in platelets. Expressed in a restricted set of hematopoietic cell lines including the erythroleukemia cell line K-562 and the T-cell leukemia cell lines MOLT-4 and Jurkat. Not detected in the monocyte-like cell line U- 937, the B-cell-like cell line Raji, the fibroblast cell lines TK and HeLa, or the natural killer cell lines NKL, NK 62 and YT.
