FAZF is ubiquitously expressed. Multiple human tissue northern blot (Clontech) was probed using radiolabeled restriction fragment from clone 8-1. Lane 1, spleen; lane 2, thymus; lane 3, prostate; lane 4, testis; lane 5, ovary; lane 6, small intestine; lane 7, colon; lane 8, peripheral blood mononuclear leukocyte. Longer exposure of this blot showed a 1.4-kb FAZF band in all tissues except testis.
