| Abstract: | In this study, sequencing of voltage-dependent anion channel 2 (VDAC2, porin-2) cDNA from bovine testis is reported. High identity to the murine, rabbit, and human subtypes at both the nucleotide and amino acid levels is demonstrated. mRNA analysis revealed expression of VDAC2 in bovine testis, whereas high levels of VDAC2 proteins were found in late spermatocytes, spermatids, and spermatozoa. In contrast, VDAC1 (porin-1) is exclusively localized in Sertoli cells. The possible role of testicular VDAC2 in providing energy metabolites and in germ cell apoptosis is discussed. |
