SH2 도메인 함유 단백질 1A는 SH2D1A[5][6][7]유전자에 의해 인간에서 암호화되는 단백질이다.그것은 종종 SLAM 관련 단백질(SLAM-associated protein, 기호 SAP)이라고 불리며, 여기서 "SLAM"은 신호성 림프구 활성화 분자를 가리킨다.SLAM 시그널링에서 역할을 하는 것은 SH2 도메인을 포함하는 분자(이러한 분자군의 일부)이다.추정 기능은 Fyn 및 포스파타아제 경쟁제품에 대한 어댑터로서 SLAM 패밀리 기능의 변조를 초래합니다.SAP는 자가면역에 [8]관여하고 있으며, 그 돌연변이는 X-연관 림프증식성 질환과 관련되어 있다.이 유전자의 질병을 일으키는 변이가 적어도 32개 발견되었다.[9]
