has published the discovery and preclinical characterization data on H3B-8800, its oral, first-in-class modulator of the SF3b spliceosome complex, in the most recent issue of Nature Medicine, the company said.
Objective: The spliceosome is a ribonucleoprotein machine that excises introns from pre-messenger RNAs.

Mutations in U4atac snRNA, a component of the minor spliceosome in the developmental disorder MOPD 1.
Recent studies (48) suggest that even in elderly patients without MDS-like cytogenetics or antecedent MDS, the mutational profile of AML is often MDS-like, with frequent mutations of spliceosome genes, ASXL1, and EZH2 in these elderly patients with genetically MDS-like, but clinically de novo AML.
mRNA splicing is usually carried out by the spliceosome in the nucleus; however, the sequences around the 5' and 3' splice sites in HAC1 precursor mRNA do not match the consensus sequence (GT-AG or AT-AC).
To this end, small antisense oligonucleotides (AONs) sequences are designed to bind to exon splice junctions, masking them from the spliceosome.
The spliceosome features recognition of either end of scores of introns for each "gene".
In addition, gene-ontology analysis identified the cellular component enrichment of spliceosome and ribosome (Fig.
RNA helicase p68 was first identified as 65 kDa protein (p65) by methylene blue-mediated cross-linking (MB-cross- linked) interacting with the U1snRNP when it was bound at5`ss of intron in spliceosome formation by Liu et al.
The spliceosome recognizes specific signals in the nascent RNA, part of which is the consensus splice sequence at the splice junctions and a pyrimidine (cytosine and thymine or uracil) rich tract [11].
Non-canonical splicing, known to account for the remaining rare 1% of all splicing, occurs when the minor spliceosome excises introns with different splice sites [20].
