Expression of a truncated form of KIT tyrosine kinase in human spermatozoa correlates with sperm DNA integrity

Abstract excerpt

BACKGROUND: TR-KIT, a truncated form of KIT (the KITL receptor), corresponding to the c-terminal half of the intracellular split tyrosine kinase domain, is expressed during the haploid stages of mouse spermatogenesis, and is one of the candidate sperm factors possibly involved in egg activation at fertilization. METHODS: Immunocytochemistry of adult human testis, and studies of human semen samples from volunteer...
