We identified a novel gene, which encodes a 265-amino-acid sequence with a
thrombospondin (TSP) type 1 motif. Unlike the other secretory proteins of the TSP family, this
gene encodes no apparent secretion cleavage site, but has a putative nuclear localization
signal. Northern blot analysis showed transient expression in the central nervous system
(CNS) during development. In situ hybridization showed its expression in the dorsal part of
the neural tube on 10 and 12 dpc, especially in the boundary region between roof plate and …
