Protein kinase C (PKC) has been implicated in the Wnt signaling pathway; however, its molecular role is poorly understood. We identified novel genes encoding delta-type PKC in the Xenopus EST databases. Loss of PKC delta function revealed that it was essential for convergent extension during gastrulation. We then examined the relationship between PKC delta(More)
During Xenopus development, embryonic cells dramatically change their shape and position. Rho family small GTPases, such as RhoA, Rac, and Cdc42, play important roles in this process. These GTPases are generally activated by guanine nucleotide exchange factors (GEFs); however, the roles of RhoGEFs in Xenopus development have not yet been elucidated. We(More)
