ABSTRACT
The zebrafish biklf gene encodes a novel Kruppel-like transcription factor containing three contiguous zinc fingers at the C-terminus. Expression of biklf is detected from the shield stage onward in the developing prechordal plate, and as a 'baseball seam'-like lateral stripe beginning at the end of gastrulation. The latter expression domain is suppressed in the swirl mutant in which bmp2b is disrupted. At the 5-somite stage the lateral expression domain separates into two distinct stripes, one in the ectoderm, the other in blood islands in the lateral plate mesoderm. Blood island staining of biklf continues through somitogenesis as the most prominent area of biklf expression.
