Function

RNA-binding protein that acts as a key regulator of N6-methyladenosine (m6A) methylation of RNAs, thereby regulating different processes, such as hematopoietic cell homeostasis, alternative splicing of mRNAs and X chromosome inactivation mediated by Xist RNA (PubMed:27602518). Associated component of the WMM complex, a complex that mediates N6-methyladenosine (m6A) methylation of RNAs, a modification that plays a role in the efficiency of mRNA splicing and RNA processing (By similarity). Plays a key role in m6A methylation, possibly by binding target RNAs and recruiting the WMM complex (PubMed:27602518). Involved in random X inactivation mediated by Xist RNA: acts by binding Xist RNA and recruiting the WMM complex, which mediates m6A methylation, leading to target YTHDC1 reader on Xist RNA and promoting transcription repression activity of Xist (PubMed:27602518). Required for the development of multiple tissues, such as the maintenance of the homeostasis of long-term hematopoietic stem cells and for megakaryocyte (MK) and B-cell differentiation (By similarity). Regulates megakaryocyte differentiation by regulating alternative splicing of genes important for megakaryocyte differentiation; probably regulates alternative splicing via m6A regulation (PubMed:26575292). Required for placental vascular branching morphogenesis and embryonic development of the heart and spleen (By similarity). Acts as a regulator of thrombopoietin response in hematopoietic stem cells by regulating alternative splicing of MPL (By similarity). May also function as an mRNA export factor, stimulating export and expression of RTE-containing mRNAs which are present in many retrotransposons that require to be exported prior to splicing (PubMed:17001072, PubMed:19786495). High affinity binding of pre-mRNA to RBM15 may allow targeting of the mRNP to the export helicase DBP5 in a manner that is independent of splicing-mediated NXF1 deposition, resulting in export prior to splicing (PubMed:17001072, PubMed:19786495). May be implicated in HOX gene regulation (PubMed:11344311).

Notes

ab315457 is the carrier-free version of Anti-Rbm15/OTT antibody [EPR28158-87] ab315456.

Our RabMAb® technology is a patented hybridoma-based technology for making rabbit monoclonal antibodies. For details on our patents, please refer to RabMAb® patents.

This product is a recombinant monoclonal antibody, which offers several advantages including:

  • - High batch-to-batch consistency and reproducibility
  • - Improved sensitivity and specificity
  • - Long-term security of supply
  • - Animal-free batch production

For more information, read more on recombinant antibodies.

Our carrier-free antibodies are typically supplied in a PBS-only formulation, purified and free of BSA, sodium azide and glycerol. The carrier-free buffer and high concentration allow for increased conjugation efficiency.

This conjugation-ready format is designed for use with fluorochromes, metal isotopes, oligonucleotides, and enzymes, which makes them ideal for antibody labelling, functional and cell-based assays, flow-based assays (e.g. mass cytometry) and Multiplex Imaging applications.

Use our conjugation kits for antibody conjugates that are ready-to-use in as little as 20 minutes with 1 minute hands-on-time and 100% antibody recovery: available for fluorescent dyes, HRP, biotin and gold.

This product is compatible with the Maxpar® Antibody Labeling Kit from Fluidigm, without the need for antibody preparation. Maxpar® is a trademark of Fluidigm Canada Inc.

Activity summary

Rbm15 also known as OTT is a multifunctional RNA-binding protein with a mass of approximately 82 kDa. This protein participates in various cellular processes by binding to RNA molecules influencing their processing and stability. It is expressed in numerous tissues including hematopoietic cells in the bone marrow and fetal liver. The characteristic expression indicates its importance in developmental and cellular contexts.

Biological function summary

Rbm15 plays a role in the regulation of mRNA splicing and transcriptional activation. It functions as part of the methyltransferase complex which involves the methylation of mRNA as a post-transcriptional modification contributing to RNA stability and translation efficiency. This action suggests its involvement in gene expression regulation and cellular differentiation.

Pathways

Rbm15 interacts closely with the Notch signaling pathway which is significant for cell fate determination and differentiation. Rbm15 partners with other proteins such as Numb to mediate repression or activation of Notch-related transcriptional activity. Also Rbm15 affects signaling pathways through interactions with Wnt proteins which play an important role in embryonic development and cell proliferation.

Associated diseases and disorders

Rbm15 has associations with acute megakaryoblastic leukemia (AMKL) and myelodysplastic syndromes (MDS). In AMKL Rbm15 forms a fusion protein with MKL1 resulting from chromosomal translocations which contributes to leukemogenesis. Understanding its interaction with MKL1 and other fusion partners provides insight into the pathogenesis of these hematological disorders. The study of Rbm15's role in these contexts holds potential for therapeutic advances.
