Summary: Enables mRNA binding activity and ribosome binding activity. Involved in asymmetric neuroblast division and mitochondrion localization. Located in several cellular components, including Golgi apparatus; mitochondrion; and mitotic spindle. Is extrinsic component of mitochondrial outer membrane. Part of outer mitochondrial membrane protein complex. Is expressed in several structures, including embryonic/larval midgut primordium; ganglia; larval muscle cell; mesoderm; and visceral muscle primordium. Orthologous to human CLUH (clustered mitochondria homolog). [provided by Alliance of Genome Resources, Dec 2024]

What's a GeneRIF?

Clueless forms dynamic, insulin-responsive bliss particles sensitive to stress.
Title: Clueless forms dynamic, insulin-responsive bliss particles sensitive to stress.
Clu is upstream of and binds to VCP in vivo and promotes VCP-dependent Marf degradation in vitro Marf accumulates in whole muscle lysates of clu-deficient flies and is destabilized upon Clu overexpression. Thus, Clu is essential for mitochondrial homeostasis and functions in concert with Parkin and VCP for Marf degradation to promote damaged mitochondrial clearance.
Title: Drosophila clueless is involved in Parkin-dependent mitophagy by promoting VCP-mediated Marf degradation.
Clu directly modulates mitochondrial function, and that Clu's function contributes to the PINK1-Park pathway of mitochondrial quality control.
Title: Clueless, a protein required for mitochondrial function, interacts with the PINK1-Parkin complex in Drosophila.
Clueless (clu) is a novel regulator of aPKC activity.
Title: Clueless regulates aPKC activity and promotes self-renewal cell fate in Drosophila lgl mutant larval brains.
The results suggest Clu functions upstream of electron transport and oxidative phosphorylation, has a role in suppressing oxidative damage in the cell, and that lack of Clu's specific function causes mitochondria to mislocalize.
Title: Drosophila clueless is highly expressed in larval neuroblasts, affects mitochondrial localization and suppresses mitochondrial oxidative damage.
strong clu mutations resemble park mutations in their effects on mitochondrial function and that the two genes interact genetically
Title: Clueless, a conserved Drosophila gene required for mitochondrial subcellular localization, interacts genetically with parkin.
