The insertion of a PGK-neo cassette into exon 2 disrupted sequence encoding the third transmembrane domain. Though Northern blot analysis identified several aberrant transcripts in homozygous mutant mice, no normal transcript was detected. Binding assays using a labeled thromboxane agonist indicated an absence of functional receptors in both thymocytes and renal sections obtained from homozygous mutant mice. (J:52125)
