Summary: Enables Arp2/3 complex binding activity. Involved in several processes, including actin cortical patch assembly; cellular bud site selection; and positive regulation of Arp2/3 complex-mediated actin nucleation. Acts upstream of or within reticulophagy. Located in actin cortical patch and nucleus. Part of actin cytoskeleton-regulatory complex. Human ortholog(s) of this gene implicated in neurodegeneration with brain iron accumulation. Orthologous to human REPS1 (RALBP1 associated Eps domain containing 1).

Eps15/Pan1p is a master regulator of the late stages of the endocytic pathway.
Title: Eps15/Pan1p is a master regulator of the late stages of the endocytic pathway.
Cooperative regulation of endocytic vesicle transport by yeast Eps15-like protein Pan1p and epsins.
Title: Cooperative regulation of endocytic vesicle transport by yeast Eps15-like protein Pan1p and epsins.
TORC2-dependent phosphorylation of the coat protein Pan1 by Akl1 controls endocytosis dynamics in Saccharomyces cerevisiae.
Title: Target of rapamycin complex 2-dependent phosphorylation of the coat protein Pan1 by Akl1 controls endocytosis dynamics in Saccharomyces cerevisiae.
Thus Pan1 phosphorylation is part of a novel mechanism that regulates endocytic compartment interactions with each other and with actin cables.
Title: Yeast Eps15-like endocytic protein Pan1p regulates the interaction between endocytic vesicles, endosomes and the actin cytoskeleton.
A region of Pan1 spanning the second EH domain and central region was critical for viability and endocytosis. Other regions of Pan1 supported viability and not endocytosis, suggesting that Pan1 may have an additional role independent of endocytosis.
Title: Pan1 regulates transitions between stages of clathrin-mediated endocytosis.
N-terminal part of Pan1's central coiled-coil region binds End3 C-terminus.
Title: Targeted disruption of an EH-domain protein endocytic complex, Pan1-End3.
Pan1 contains functional nuclear localization signals (NLS) and a NES and appears to shuttle in certain circumstances

Title: Pan1p: an actin director of endocytosis in yeast.
Pan1 and the type I myosins interactions promote an actin activity important at a late stage in endocytic internalization.
Title: Interaction of the endocytic scaffold protein Pan1 with the type I myosins contributes to the late stages of endocytosis.
Pan1p, and possibly other components of the actin cytoskeleton, are necessary to properly regulate growth of dividing cells in response to the presence of some alternative carbon sources (oleate) in the medium.
Title: Pan1p, an actin cytoskeleton-associated protein, is required for growth of yeast on oleate medium.
