Arabidopsis TITAN LIKE is required for U12-type intron splicing, especially for AT-AC subtypes

Tomoko Niwa, Junshin Miyamoto, Nao Iwase, Haruka Iwai, Takaaki Kojima, Takamasa Suzuki

This study shows that Arabidopsis TTL is essential for U12-type intron splicing, especially AT-AC introns, and identifies distinct spliceosomal functions from DROL1.

DROL1 subunit of U5 snRNP in the spliceosome is specifically required to splice AT--AC-type introns in Arabidopsis

Takamasa Suzuki, Tomomi Shinagawa, Tomoko Niwa, Hibiki Akeda, Satoki Hashimoto, Hideki Tanaka, Yoko Hiroaki, Fumiya Yamasaki, Hiroyuki Mishima, Tsutae Kawai, Tetsuya Higashiyama, Kenzo Nakamura

This study identifies DROL1 as an Arabidopsis U5 snRNP subunit required for splicing AT-AC-type introns, showing its role in plant growth and development through RNA-Seq analysis of mutants.
