| 背景 | RNA-splicing ligase RTCB is a ~55 kDa protein. 3'-5' RNA ligase, catalytic subunit of the tRNA-splicing ligase complex (tRNA-LC), which is involved in the enzyme-dependent maturation of intron-containing pre-tRNAs. Functions downstream of the tRNA-splicing endonuclease that removes introns, ligating the two generated halves via phosphodiester bond formation. The ligation reaction, which requires guanosine triphosphate (GTP) and Mn(2+), proceeds through three metal-dependent steps. The first step requires ZBTB8OS/Archease and involves the guanylylation of RTCB at its active site histidine, forming a covalent GMP-histidine intermediate. Before the second step, RTCB also hydrolyzes the 2',3'-cyclic phosphate (cP) at the 3' end of the 5' tRNA exon, typically generated by the tRNA-splicing endonuclease, producing a 3' phosphate. 1.

A549 cells were fixed with 4% paraformaldehyde for 20 minutes, followed by blocking with 5% goat serum for 1 hour. The cells were then incubated with a primary antibody targeting RTCB (HV728014) at a concentration of 31.5 ug/ml overnight at 4°C. Afterward, the cells were incubated with a secondary antibody, Goat Anti-Rabbit IgG (Alexa Fluor-488) for 50 minutes at room temperature. The localization of RTCB was visualized (shown in green), and nuclear DNA was stained with DAPI (shown in blue).
Western blot analysis was performed using anti-RTCB polyclonal antibody at 1μg/ml on various samples.
