Background Information

WD repeat domain phosphoinositide-interacting protein 4 (WDR45) is also named as WDRX1, WDRXI4 and WIPI4, and belongs to the WD repeat PROPPIN family. WDR45 is highly conserved in mammals, and the amino acid sequences of the human, mouse, pig, bovine and horse protein have more than 97% identity (PMID:20505359). WDR45 is component of the autophagy machinery that controls the major intracellular degradation process (PMID:23435086, PMID:28561066). Together with WIPI1, WIPI2 and WIPI3/WDR45B, it forms the WIPI (WD repeat domain, phosphoinositide interacting) protein family. And this is why WDR45 is also known as WIPI4 (PMID:11814058). The best characterized molecular function of WDR45 is promoting lipid transfer together with ATG2 proteins between adjacent membranes. This function at the phagophore-ER membrane contact sites is important for autophagy (PMID:30185561, PMID:31721365). WDR45 is activated by the STK11/AMPK signaling pathway upon starvation. WDR45 is involved in autophagosome assembly downstream of WIPI2, regulating the size of forming autophagosomes (PMID:28561066).
