  • Antibodies to a testis-specific differentiation-regulatory factor
    Patent number: 7288635
    Abstract: A gene expressed specifically in the testis has been unexpectedly isolated in the course of studies of the expression of a gene encoding an unknown protein that triggers cell death. The isolated gene was a novel gene sequence that had no significant homologue in the database. This gene was also found to be involved in the regulation of differentiation in the testis and to encode a protein, Tesmin, which may regulate the differentiation of spermatogeneous cells into primary spermatocytes. Tesmin proteins are described herein, as are antibodies that bind to such proteins.

  • Protein and gene involved in myocyte differentiation
    Publication number: 20040086933
    Abstract: A novel gene was unexpectedly isolated in an attempt to isolate a gene specifically expressed in immortalized cells via antibody screening using an antibody raised against a protein occurring specifically in immortalized cells. The gene thus isolated shares no sequence homology with the entries deposited in the database and was strongly expressed in skeletal muscles and undifferentiated cells. The protein encoded by this gene inhibits the differentiation of myoblasts into myotubes. It also inhibits the transactivation function of p53, a transcription factor involved in tumor suppression.
