Sperm Protein 17 Is Expressed in Human Somatic Ciliated Epithelia

1 Apr 2004

Abstract excerpt

It was once believed that sperm protein 17 (Sp17) was expressed exclusively in the testis and that its sole function was to bind to the oocyte during fertilization. However, immunohistochemistry of the human respiratory airways and reproductive systems show that it is abundant in ciliated cells but not in human cells with stereocilia and microvilli. The high degree of sequence conservation throughout its...
