NOSTRIN is a prototypic PCH/F‑BAR protein with an N‑terminal F‑BAR domain mediating membrane association and a C‑terminal SH3 domain representing a docking platform for various proteins. Human NOSTRIN has recently been shown to function as an adaptor protein in caveolar trafficking of endothelial nitric oxide synthase (eNOS). An N‑terminally shortened variant of the protein, referred to as NOSTRINβ, mainly localizes to the cell nucleus and may play a role in gene regulation. Both NOSTRIN variants are up‑regulated under certain (pathological) conditions, which may contribute to the progression of the respective diseases.

The PACSIN Proteins and their Role in Membrane Trafficking

Markus Plomann, Matthias Mörgelin and Sylvia Schael

PACSIN 1/syndapin 1 was originally identified by its drastic expression decrease during CNS repair processes and by virtue of its binding to the GTPase dynamin. The three family members play important...

F‑BAR Domain Proteins in Schizosaccharomyces pombe

Rachel H Roberts-Galbraith and Kathleen L. Gould

S chizosaccharomyces pombe is a simple model organism ideal for study of conserved proteins of interest. The genome of S. pombe encodes seven proteins containing F‑BAR domains, including f...

The CIP4 Family of F‑BAR Domain‑Containing Proteins

Marcia Toguchi and Pontus Aspenström

The F‑BAR family of proteins has emerged as important coordinators of signaling pathways that regulate actomyosin assembly and membrane dynamics. This review article will focus on the Cdc42̴...

FES and FER: The F‑BAR Domain‑Containing Protein‑Tyrosine Kinases

Waheed Sangrar, Andrew W. Craig and Peter A. Greer

FES and FER are the only two members of a distinct subgroup of the protein‑tyrosine kinase (PTK) family. What distinguishes them from other PTKs and indeed all other kinases, are their unique am...

PSTPIP1 and PSTPIP2/MAYP

Violeta Chitu and E. Richard Stanley

PSTPIP1 and PSTPIP2 are expressed predominantly in the hematopoietic system where their C‑terminal tyrosine phosphorylation is regulated by PEST family phosphatases. Both proteins deform membran...

Boomerangs, Bananas and Blimps: Structure and Function of F‑BAR Domains in the Context of the BAR Domain Superfamily

Adam Frost, Vinzenz M. Unger and Pietro De Camilli

Proteins that belong to the BAR (Bin, Amphiphysin, RVS) domain superfamily are alpha‑helical bilayer‑binding modules that have evolved to induce or stabilize membrane curvature during cell...

The Budding Yeast PCH/F‑BAR Proteins

Alan L. Munn

The budding yeast Saccharomyces cerevisiae genome encodes two classical Pombe Cdc15 Homology (PCH) proteins: Hof1p (or Cyk2p) and Bzz1p (or Lsb7p). Like mammalian PCH proteins, both have an N‑te...

Gas7

Wenlynn B. Su, Jhong-Jhe You, Bo-Tsang Huang, Viswanathan Sivakumar, Shauh-Der Yeh and Sue Lin-Chao

Gas7 (growth‑arrest specific gene 7) has recently been classified to be a member of the Pombe Cdc 15 homology (PCH) family and belongs to the proline, serine, threonine‑rich phosphatase in...
