TREML4 (Triggering receptor expressed on myeloid cells-like
4; also TLT4) is a 53-55 kDa member of the Ig superfamily. It is likely expressed by leukocytes, and
based on its structure, may act as an activating receptor. Mature mouse TREML4 is a type I transmembrane
(TM) glycoprotein that is 235 amino acids (aa) in length. It contains a 171 aa
extracellular region (aa 29-199) with a V-type Ig-like domain (aa 29-122); the
TM segment contains one
