abstract = {During clathrin-mediated endocytosis, a complex and dynamic
network of protein-membrane interactions cooperate to
achieve membrane invagination. Throughout this process in
yeast, endocytic coat adaptors, Sla2 and Ent1, must remain
attached to the plasma membrane to transmit force from the
actin cytoskeleton required for successful membrane
invagination. Here, we present a cryo-EM structure of a
16-mer complex of the ANTH and ENTH membrane-binding domains
from Sla2 and Ent1 bound to PIP$_2$ that constitutes the
anchor to the plasma membrane. Detailed in vitro and in vivo
mutagenesis of the complex interfaces delineate the key
interactions for complex formation and deficient cell growth
phenotypes demonstrate its biological relevance. A
hetero-tetrameric unit binds PIP$_2$ molecules at the
ANTH-ENTH interfaces and can form larger assemblies to
contribute to membrane remodeling. Finally, a time-resolved
small-angle X-ray scattering study of the interaction of
these adaptor domains in vitro suggests that ANTH and ENTH
domains have evolved to achieve a fast subsecond timescale
assembly in the presence of PIP$_2$ and do not require
further proteins to form a stable complex. Together, these
findings provide a molecular understanding of an essential
piece in the molecular puzzle of clathrin-coated endocytic
sites.},
