Short name: FNBP1/FBP17

Family relationships

None.

Description

Formin-binding protein 1 (FNBP1, also known as formin-binding protein 17) contains a N-terminal FER-CIP4 homology (FCH) domain and a C-terminal SH3 domain. It belongs to the CIP4 (Cdc42 interacting protein-4) subfamily of the F-BAR (F for FCH, Fer-CIP4 homology domain) protein family. The F-BAR proteins have been implicated in cell membrane processes such as membrane invagination, tubulation and endocytosis [PMID: 23384583]. FNBP1 was originally isolated as a molecule that binds to the proline-rich region of formin [PMID: 8605874]. It induces tubular membrane invaginations and participates in endocytosis [PMID: 15252009]. It interacts with sorting nexin, SNX2 and is linked to acute myelogeneous leukemia [PMID: 11438682].
