Characterization of MAP c21873-1 as a new counter-selectable marker for unmarked genetic modification of Pichia pastoris

Liu M, Zhou S, Cao Y, Yang K, Xiao Y, Wang W (2024) Characterization of MAP c21873-1 as a new counter-selectable marker for unmarked genetic modification of Pichia pastoris. Microb Cell Fact 23(1):224. doi: 10.1186/s12934-024-02496-w PMID: 39118053

Objective: To establish a new counter-selectable marker-based strategy for seamless modification with high efficiency and low toxicity.

Summary: Development of MAP c21873-1 as a novel counter-selectable marker which could perform efficient gene knock-in by site-directed HR.

Usage: MazF, c21873-1, c23467 and twenty-four RIPs were selected to construct a phylogenetic tree to investigate their relationships in the evolutionary history. The phylogenetic analysis demonstrates that c21873-1 and c23467 are closely relative to type I RIPs such as PAP-S and saporin (PR-01).
