Caps-ac4C: an effective computational framework for identifying N4-acetylcytidine sites in human mRNA based on deep learning.

N4-acetylcytidine (ac4C) is a crucial post-transcriptional modification in human mRNA, involving the acetylation of the nitrogen atom at the fourth position of cytidine. This modification, catalyzed by N-acetyltransferases such as NAT10, is primarily found in mRNA's coding regions and enhances translation efficiency and mRNA stability. ac4C is closely associated with various diseases, including cancer.

Shotgun and targeted proteomics of Mycolicibacterium smegmatis highlight the role of arginine phosphorylation in the functional adaptation to its environment.

Although the phosphorylation of serine (S), threonine (T), and tyrosine (Y) is well-established, arginine phosphorylation (pR) has recently garnered significant attention due to its crucial role in bacteria pathogenicity and stress response. Mycolicibacterium smegmatis, a nonpathogenic surrogate of Mycobacterium tuberculosis, serves as a model for studying mycobacterial pathogenesis. A recent proteomics study identified six pR proteins in M.
