| Summary: | Androgen has an important role in regulation epididymal sperm maturation Epididymal sperm maturation is occurs via interactions between sperm and proteins secreted by epididymal genes that are specifically expressed in a region-specific manner. Mice CD52 exhibited expression in all regions in epididymis. However, the regulation of its expression by androgen is needed to be known as a gene candidate that involved in sperm maturation. Objective: This study was aimed to analyze regulation of mice CD52 expression by androgen and a bioinformatics analysis was performed to predict functional domains of CD52. Methods: bioinformatics analysis using Motif Scan. For experiment, mice divided into 5 groups. The groups were control was injected ethanol 0,1 mL/day and others groups were 3, 5, 10, and 15 day used a androgen receptor antagonist, flutamide that dilute in ethanol at a dose of 50 mg/kg/day. And then quantitative real-time RT-PCR was used to analyse expression of CD52 and it’s normalized to Beta actin. Result: CD52 contained a two potential phosphorylation sites for protein kinase C and casein kinase II, N-myristoylation, and N-glycosylation that showed CD52 is secretory protein and predict it’s attached to sperm membrane. Expression of CD52 was decrease about 93% than control. Conclusion: CD52 expression depend on androgen.
