Genomics, 1999•ElsevierFLRT1, FLRT2, and FLRT3 comprise a novel gene family isolated in a screen for
extracellular matrix proteins expressed in muscle. The three genes encode putative type I
transmembrane proteins, each containing 10 leucine-rich repeats flanked by N-terminal and
C-terminal cysteine-rich regions, a fibronectin/collagen-like domain, and an intracellular tail.
FLRT1 is expressed in kidney and brain, FLRT2 is expressed in pancreas, skeletal muscle,

FLRT1, FLRT2, and FLRT3 comprise a novel gene family isolated in a screen for extracellular matrix proteins expressed in muscle. The three genes encode putative type I transmembrane proteins, each containing 10 leucine-rich repeats flanked by N-terminal and C-terminal cysteine-rich regions, a fibronectin/collagen-like domain, and an intracellular tail. FLRT1 is expressed in kidney and brain, FLRT2 is expressed in pancreas, skeletal muscle, brain, and heart, and FLRT3 is expressed in kidney, brain, pancreas, skeletal muscle, lung, liver, placenta, and heart. FLRT1 localized to 11q12–q13, FLRT2 to 14q24–q32, and FLRT3 to 20p11. When expressed in SF9 and COS-1 cells, FLRT1 and FLRT2 migrate as 90- and 85-kDa proteins, respectively, and both are glycosylated. Given the overall structure of the three proteins, a function in cell adhesion and/or receptor signaling is predicted.
