Kin-1 transcript ID is GRMZM2G158394. This is the ID you have to use on "the maize efp browser" web site.
About expression profile, you can also search kin-1 ESTs (using BLASTn by aligning kin-1 nucleotide sequence on maize ESTs). I quickly tried, there are "only" 425 ESTs. And then check what tissue these ESTs come from.
