Summary: Enables myosin V binding activity. Involved in Golgi distribution to daughter cells; endoplasmic reticulum inheritance; and mitochondrion inheritance. Acts upstream of or within intracellular distribution of mitochondria. Located in several cellular components, including cellular bud neck; cellular bud tip; and incipient cellular bud site. Is active in mitochondrion. [provided by Alliance of Genome Resources, Dec 2024]

What's a GeneRIF?

The abundance of active Ypt11 forms is controlled by phosphorylation status and degradation.
Title: Mitochondrial association, protein phosphorylation, and degradation regulate the availability of the active Rab GTPase Ypt11 for mitochondrial inheritance.
Myo2 drives anterograde mitochondrial movements in budding yeast and this activity is supported by Ypt11 and Mmr1.
Title: The myosin-related motor protein Myo2 is an essential mediator of bud-directed mitochondrial movement in yeast.
required for the vectorial actin-dependent movement of the late Golgi from the mother cell toward the emerging bud
Title: Ypt11 functions in bud-directed transport of the Golgi by linking Myo2 to the coatomer subunit Ret2.
These findings provide insight into novel gene functions and classify the uncharacterized Rab proteins Ypt10p (YBR264C) as being involved in endocytic function and Ypt11p (YNL304W) as being localized to the endoplasmic reticulum.
Title: Bioinformatic and comparative localization of Rab proteins reveals functional insights into the uncharacterized GTPases Ypt10p and Ypt11p.
retention of mitochondria in the bud was compromised in YPT11 and MYO2 mutants
Title: A type V myosin (Myo2p) and a Rab-like G-protein (Ypt11p) are required for retention of newly inherited mitochondria in yeast cells during cell division.
we show that, in human cells, after heterologous expression of GFP-Ypt11 (where GFP stands for green fluorescent protein), the protein is targeted to transferrin-positive recycling endosomes.
Title: Yeast Ypt11 is targeted to recycling endosomes in mammalian cells.

Preferred Names: Rab family GTPase YPT11

NP_014095.2

Rab GTPase; Myo2p-binding protein implicated in mother-to-bud transport of cortical endoplasmic reticulum (ER), late Golgi, and mitochondria during cell division; function is regulated at multiple levels; abundance of active Ypt11p forms is controlled by phosphorylation status and degradation; normally a low-abundance protein whose ER localization is only detected when protein is highly over expressed
