Keyword - Viral penetration into host cytoplasm via pilus retraction (KW-1241)

Keywords navigation

Definition

Viral protein involved in the entry of the virion into the host cytoplasm via the host pili, which are retractile filaments that protrude from gram-negative bacteria. Entry of bound prokaryotic viruses such as filamentous viruses is achieved through the retraction of host pilus and translocation of the virion through the basis of the pilus to reach the host cytoplasm. Examples of bacteriophages which utilize the host cell pilus to penetrate into host cytoplasm are bacteriophages M13, f1, fd, R17.
