SH2 domain-containing protein 1B2 (Sh2d1b2)

Cytoplasmic adapter regulating receptors of the signaling lymphocytic activation molecule (SLAM) family. In SLAM signaling may cooperate with Sh2d1a/SAP.

Plays a role in regulation of effector functions of natural killer (NK) cells by controlling signal transduction through Cd244/2b4. However, conflicting results are reported which may reflect the use of different strain backgrounds.
