Application Abreviews Notes
Flow Cyt 1/250.
IHC-P 1/100. Perform heat mediated antigen retrieval with Tris/EDTA buffer pH 9.0 before commencing with IHC staining protocol.
WB 1/1000 - 1/10000. Detects a band of approximately 53 kDa (predicted molecular weight: 53 kDa).
ICC/IF 1/100.


  • Function

    Regulator of post-transcriptional mitochondrial gene expression, required for assembly of the mitochondrial ribosome and for recruitment of mRNA and lncRNA. Binds RNAs containing the 14 base G-rich element. Preferentially binds RNAs transcribed from three contiguous genes on the light strand of mtDNA, the ND6 mRNA, and the long non-coding RNAs for MT-CYB and MT-ND5, each of which contains multiple consensus binding sequences.
  • Sequence similarities

    Contains 3 RRM (RNA recognition motif) domains.
  • Cellular localization

    Cytoplasm. Mitochondrion matrix > mitochondrion nucleoid. Forms granules that colocalize with foci of newly synthesized mtRNA next to mitochondrial nucleoids.

  • Immunohistochemical analysis of paraffin-embedded Human liver tissue labeling GRSF1 with ab194358 at 1/100 dilution, followed by Goat Anti-Rabbit IgG H&L (HRP) (ab97051) at 1/500 dilution. Counter stained with Hematoxylin.

    Perform heat mediated antigen retrieval with Tris/EDTA buffer pH 9.0 before commencing with IHC staining protocol.

  • Immunofluorescent analysis of 4% paraformaldehyde-fixed, 0.1% Triton X-100 permeabilized HeLa cells labeling GRSF1 with ab194358 at 1/100 dilution, followed by Goat anti-rabbit IgG (Alexa Fluor® 488) (ab150077) secondary antibody at 1/400 dilution. The nuclear counter stain is DAPI (blue).

  • Flow cytometry analysis of HeLa cells labelling GRSF1 (red) with purified ab194358 at dilution of 1/250. The secondary antibody used was Alexa Fluor® 488 goat-anti-rabbit IgG (1/2000). Cells were fixed with 4% paraformaldehyde and permeabilised with 90% methanol. Isotype control antibody was Rabbit monoclonal IgG (black). The blue line shows cells without incubation with primary antibody and secondary antibody.
