TREML4/TLT-4 Products

Description

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 Lys residue.  There is one splice variant that shows a deletion of aa 21-24, a segment that lies in the putative signal sequence.  Rodent and human TREML4 are highly divergent, and thus over aa 25-195, mouse TREML4 shares 78% aa sequence identity with rat TREML4, but only 52% aa sequence identity with human TREML4.
