GINS complex subunit 1
Psf1, GINS1, CDC101
The yeast heterotetrameric GINS complex is made up of Sld5 (GINS4; MIM 610611), Psf1, Psf2 (GINS2; MIM 610609), and Psf3 (GINS3; MIM 610610). The formation of the GINS complex is essential for the initiation of DNA replication in yeast and Xenopus egg extracts (Ueno et al., 2005 [PubMed 16287864]).[supplied by OMIM, Mar 2008] (from

We analyzed whether CICs acquire drug resistance after cancer drug treatment in a tumor cell allograft model in which we could identify and isolate living CICs by detecting a higher level of transcriptional activity of the PSF1 gene promoter.

OBJECTIVE: To detect the expression of PSF1 (partner of Sld five 1) in colon cancer specimens, and to explore the effect of RNA interference targeting PSF1 on the proliferation of colon cancer cells and its mechanism.

This pathway may depend on a transporter (PSF1) to mediate entry of the cytosolic peptides into a pre-Golgi compartment where they bind to class I heavy chains and promote their stable assembly with beta 2-microglobulin.
