Modulation of transcriptional regulation by LEF-1 in response to Wnt-1 signaling and association with beta-catenin.

abstract：:We have isolated a full-length mouse cDNA encoding a lysine-rich protein of 1,131 amino acids with a calculated molecular mass of 126 kDa. The protein binds in a sequence-unspecific manner to DNA, is localized exclusively in the nucleus, and contains a putative ATP binding site and a stretch of 80 amino acids with hom...
