sperm associated antigen 6; Important for structural integrity of the central apparatus in the sperm tail and for flagellar motility (By similarity) (509 aa)

nuclear RNA export factor 3; May function as a tissue-specific nuclear mRNA export factor (531 aa)

SPRY domain containing 7 (196 aa)

ring finger protein 17; Seems to be involved in regulation of transcriptional activity of MYC. In vitro, inhibits DNA-binding activity of Mad- MAX heterodimers. Can recruit Mad transcriptional repressors (MXD1, MXD3, MXD4 and MXI1) to the cytoplasm. May be involved in spermiogenesis (By similarity) (1623 aa)

testis-specific serine kinase 2; Testis-specific serine/threonine-protein kinase required during spermatid development. Phosphorylates TSKS at ’Ser-288’ and SPAG16. Involved in the late stages of spermatogenesis, during the reconstruction of the cytoplasm. During spermatogenesis, required for the transformation of a ring-shaped structure around the base of the flagellum originating from the chromatoid body (358 aa)

polymerase (RNA) II (DNA directed) polypeptide J, 13.3kDa; DNA-dependent RNA polymerase catalyzes the transcription of DNA into RNA using the four ribonucleoside triphosphates as substrates. Component of RNA polymerase II which synthesizes mRNA precursors and many functional non-coding RNAs. Pol II is the central component of the basal RNA polymerase II transcription machinery. It is composed of mobile elements that move relative to each other. RPB11 is part of the core element with the central large cleft (By similarity) (117 aa)

synaptonemal complex protein 2; Major component of the axial/lateral elements of synaptonemal complexes (SCS) during meiotic prophase. May be involved in the organization of chromatin by temporarily binding to DNA scaffold attachment regions. Requires SYCP3, but not SYCP1, in order to be incorporated into the axial/lateral elements (By similarity) (1530 aa)

DnaJ (Hsp40) homolog, subfamily B, member 13; May be involved in inhibiting testis spermatogenesis apoptosis (316 aa)
