C-type lectin-like receptor involved in natural killer cell mediated cytotoxicity and cytokine secretion in keratinocytes via its interaction with CLEC2A (PubMed:20194751, PubMed:25510854). Triggers degranulation in a SYK-dependent manner and stimulates SYK phosphotyrosinylation without recruiting SYK directly (PubMed:28082678). {ECO:0000269|PubMed:20194751, ECO:0000269|PubMed:28082678}. This is the function of ENSG00000256797 (KLRF2, killer cell lectin like receptor F2).
