title: A family of Xenopus BTB-Kelch repeat proteins related to ENC-1: new markers for early events in floorplate and placode development.
abstract: We report the expression of a family of Xenopus genes encoding BTB-Kelch repeat proteins related to mouse ENC-1. Xenopus ENC-related-1 (Xencr-1) is expressed throughout the dorsal midline in dorsal endoderm, notochord, and deep neuroectoderm cells during early neurula stages. Later, Xencr-1 expression is downregulated in the notochord in an anterior-to-posterior progression but is maintained in the floorplate and dorsal endoderm. Xencr-3 is expressed strongly in several cranial placodes during the early neurula stages, placing it among the earliest molecular markers of placode precursor populations.
