Methods for isolating K+Hnov genes are provided. The K+Hnov nucleic acid
compositions find use in identifying homologous or related proteins and
the DNA sequences encoding such proteins; in producing compositions that
modulate the expression or function of the protein; and in studying
associated physiological pathways. In addition, modulation of the gene
activity in vivo is used for prophylactic and therapeutic purposes, such
as identification of cell type based on expression, and the like.
