General description

SLAM family member 7 (UniProt Q8BHK6; also known as CD2-like receptor-activating cytotoxic cells, CRACC, Leukocyte cell-surface antigen, Novel Ly9, CD319) is encoded by the Slamf7 (also known as Cs1) gene (Gene ID 75345) in murine species. CRACC/CS1 belongs to the 6-member (SLAM/CD150, Ly-9/CD229, 2B4/CD244, CD84, NTB-A/CD352, CRACC) signaling lymphocytic activation molecule family (SLAMF) of receptors broadly expressed in hematopoietic cells. 2B4 and CD48 interact with each other, while rest of the family members act as self-ligands, where two identical molecules on the surface of two different cells can interact as receptor and ligand to each other. CRACC is synthesized with a signal peptide sequence (a.a. 1-22), the removal of which yields the mature CRACC with an extracellular region (a.a. 23-224) that contains a V-type and a C2-type Ig-like domain (a.a. 27-112 and 128-203), followed by a single transmembrane domain (a.a. 225-245) and a cytoplasmic tail (a.a. 246-333). CRACC cytoplasmic domain contains one immunoreceptor tyrosine-based switch motif (ITSM; 278-TFYSTV-283, numbering based on mature murine sequence), which upon phosphorylation (pY300) recruits SAP family adaptor EWS-Fli1-activated transcript-2 (EAT-2) for signaling transduction. CRACC can also be phosphorylated on Tyr280. Unlike pY300, pY280 mediates the inhibitory function of CRACC in NK cells. In addition to NK cells, evidence indicates that CRACC is also involved in regulating B- and T-cell functions.

Specificity

Clone 4G2 reacted with murine T lymphoma BI-141 transfectants expressing mouse CRACC but not with those transfected with other members of the SLAM family (CD84, 2B4, Ly9, Ly108 or SLAM) (Cruz-Munoz, M.E., et al. (2009). Nat. Immunol. 10(3):297-305). Expected to react with all four spliced isoforms of murine CRACC reported by UniProt (Q8BHK6).

Immunogen

Epitope: Extracellular domain.
Human IgG1 Fc -tagged recombinant mouse CRACC extracellular domain.

Application

Anti-CRACC Antibody, clone 4G2 is an antibody against CRACC for use in Flow Cytometry, Affects Function, Immunoprecipitation.
Flow Cytometry Analysis: A representative lot immunostained murine T lymphoma BI-141 transfectants expressing mouse CRACC but not those transfected with other members of the SLAM family (CD84, 2B4, Ly9, Ly108 or SLAM) (Cruz-Munoz, M.E., et al. (2009). Nat. Immunol. 10(3):297-305).
Flow Cytometry Analysis: A representative lot detected CRACC expression on the surface of many types of mouse immune system cells, including NK cells, NKT cells, B cells, DCs, macrophages and activated T cells (Cruz-Munoz, M.E., et al. (2009). Nat. Immunol. 10(3):297-305).
Affects Function: A representative lot, in combination with a rabbit anti-rat IgG, cross-linked cell surface CRACC and induced similar CRACC phosphorylation in IL-2-activated NK cells from wild-type, SAP-deficient, or EAT-2–ERT–double knock (DKO) mice (Cruz-Munoz, M.E., et al. (2009). Nat. Immunol. 10(3):297-305).
Immunoprecipitation Analysis: A representative lot, in combination with a rabbit anti-rat IgG and protein A, immunoprecipitated CRACC from lysates of IL-2-activated mouse NK cells (Cruz-Munoz, M.E., et al. (2009). Nat. Immunol. 10(3):297-305).
