SF3B14 is involved in the centrosome regulation through splicing of TUBGCP6 pre-mRNA.

Splicing precursor messenger RNA (pre-mRNA) is a critical step to produce physiologically functional protein. Splicing failure not only gives rise to dysfunctional proteins but also generates abnormal protein function, which causes several diseases. Several pre-mRNA splicing factors are reported to regulate mitosis directly at mitotic structures and/or indirectly through controlling the pre-mRNA splicing for mitotic proteins.

Detection of 30 bp DNA fragments with a sensitive modified Southern blot analysis.

To evaluate crops generated by new breeding techniques, it is important to confirm the removal of recombinant DNAs (rDNAs) derived from foreign genes including unintentionally introduced short rDNA(s). We attempted to develop a sensitive detection method for such short rDNAs using Southern blot analysis and performed a model study targeting single-copy endogenous genes in plants. To increase the detection sensitivity, the general protocol for Southern blot analysis was modified.
