    Notes: Abstract  We have isolated the chicken homeobox gene NKX2.8, which represents a novel member of the NK-2 gene family. Besides the homeodomain, the NKX2.8 protein contains two other conserved sequences, a TN and an NK2 domain. NKX2.8 is expressed in the ventral foregut, the developing heart, in the epithelial layers of the branchial arches and in the dorsal mesocardium. Thus, its expression overlaps partially, but also differs significantly from another chicken tinman orthologue, the NKX2.5 gene. It is suggestive that NKX2.8 and NKX2.5 play a cooperative role in early heart development.

    Notes: Averaged projections of individual glutamine synthetase molecules have been obtained by using electron microscopy and image processing. The methodology of correlation averaging under low dose conditions is described in detail. Because of their low signal-to-noise ratio, images made under low dose conditions cannot be directly interpreted in terms of high resolution features. Computer averaging of these images reveals a division of the subunit projection into two domains whose sizes agree with results of Lei et al [2] limited proteolysis experiments.
