Domain (CC)
The ITSMs (immunoreceptor tyrosine-based switch motifs) with the consensus sequence T-X-Y-X-X-[VI] present in SLAM family receptors have overlapping specificity for activating and inhibitory SH2 domain-containing binding partners. Especially they mediate the interaction with the SH2 domain of SH2D1A and SH2D1B. A 'three-pronged' mechanism is proposed involving threonine (position -2), phosphorylated tyrosine (position 0) and valine/isoleucine (position +3).
