SidC is one of the effectors delivered by Legionella pneumophila into the host cell. Like its paralogue SdcA, SidC anchor on the Legionella-containing vacuole (LCV) through binding to phosphatidylinositol-4-phosphate (PI(4)P) to facilitate the recruitment of endoplasmic reticulum (ER) proteins. SidC is organised into four domains that are packed into an arch-like shape: the N- terminal SNL domain (Pfam:PF18219), the INS domain (which is inserted within the SNL domain), the PI(4)P binding domain or P4C domain (this entry), and a C-terminal domain (Pfam:PF20875). The lipid binding domain shows a four alpha-helix bundle with one end sealed by a C-terminal short beta hairpin and a highly positively charged pocket at the other end formed by two loops connecting the alpha-helices. This pocket is thought to be the binding site, responsible for the stimulation of the E3 ligase activity of the SNL domain [1].

This is the N-terminal domain of SidC present in Legionella pneumophilia. SidC appears to be involved in modulating mammalian trafficking by promoting the communication between ER-derived vesicles and the Legionella containing vacuole. The N-terminal domain (SidC-N) has a novel fold with 4 potential subdomains. SidC-N does not show structural similarity to any known protein domain in the protein data bank [1].
