By screening for mutations that suppress the vulval defects caused by a constitutively active let-60 ras gene, we identified six loss-of-function alleles of ksr-1, a novel C. elegans gene. Our genetic analysis showed ksr-1 positively mediates Ras signaling and functions downstream of or in parallel to let-60. In the absence of ksr-1 function, normal Ras(More)
GATA transcription factors are required for the differentiation of diverse cell types in several species. Recent evidence suggests that their biologic activities may be modulated through interaction with multitype zinc finger proteins, such as Friend of GATA-1 (FOG) and U-shaped (Ush). In cell culture, FOG cooperates with the hematopoietic transcription(More)
