TDRKH in Adult Mouse Testis. TDRKH was detected in immersion fixed frozen sections of adult mouse testis using Mouse Anti-Human TDRKH Monoclonal Antibody (Catalog # MAB6286) at 10 µg/mL overnight at 4 °C. Tissue was stained using the NorthernLights™ 493-conjugated Anti-Mouse IgG Secondary Antibody (green; Catalog # NL009) and counterstained with DAPI (blue). Specific staining was localized to cytoplasm of germ cells. View our protocol for Chromogenic IHC Staining of Frozen Tissue Sections.

Background: TDRKH

TDRKH (Tudor domain and KH domain containing protein; also TDRD2) is a 70 kDa member of the Tudor family of proteins.  It is expressed in developing spermatogonia and meiotic primary spermatocytes, but not embryonic stem cells.  TDRKH forms part of an RNA-silencing complex that safeguards the germ cell genome.  Through its 60 amino acid (aa) Tudor domain, it binds methylated PIWI (P-element-induced wimpy testis) protein and serves to position PIWI for noncoding RNA binding.  Human TDRKH is 606 aa in length.  It contains two RNA recognition KH domains (aa 52-115 and 124-190), and one methyl-binding Tudor domain (aa 353-412).  There are four potential splice forms.  Three possess a shared deletion of aa 562-606, with two of these also showing a unique deletion of aa 108-152 and 76-79, respectively; a fourth shows a two aa substitution for aa 559-606.  Over aa 206-561, human TDRKH shares 87% aa identity with mouse TDRKH.
