A 78-kDa spermatozoa motility inhibiting factor (SMIF) was purified from chicken (Gallus domesticus) seminal plasma by anion exchange (DE-53) followed by affinity chromatography on concanavalin A-Sepharose. The factor is thermostable and inhibited the spermatozoa motility in a dose dependent manner. In addition, SMIF inhibited the growth of gram negative bacteria, Pasteurella multocida but not gram positive Streptococcus equi. The factor lost its spermatozoa immobilizing property after treatment with trypsin, chymotrypsin or pepsin. The inhibition of SMIF by beta-mercaptoethanol suggest the involvement of disulfide bonds in its activity. Similarly, this property was lost in presence of chicken seminal plasma or incubating SMIF with anti-SMIF antibodies. Evidence is provided for the presence of a high molecular weight protein (> 100 kDa) in chicken seminal plasma that neutralizes the motility inhibiting property of SMIF. No significant decrease in spermatozoa ATP was observed in presence of SMIF suggesting that the loss of spermatozoa motility was due to factors other than depletion in cell's energy. Using anti-SMIF antibodies, a cross-reactive protein was identified in the blood, liver and reproductive tissues of chicken and the seminal plasma of cattle and buffalo. However, the cross-reactive protein failed to inhibit chicken spermatozoa motility. The significance of SMIF in chicken seminal plasma is discussed.
