FERM domain C-lobe of FERM domain containing 1 and 6 proteins; FRMD6 (also called willin and hEx/human expanded) is localized throughout the cytoplasm or along the plasma membrane. The Drosophilla protein Ex is a regulator of the Hippo/SWH (Sav/Wts/Hpo) signaling pathway, a signaling pathway that plays a pivotal role in organ size control and is tumor suppression by restricting proliferation and promoting apoptosis. Surprisingly, hEx is thought to function independently of the Hippo pathway. Instead it is hypothesized that hEx inhibits progression through the S phase of the cell cycle by upregulating p21(Cip1) and downregulating Cyclin A. It is also implicated in the progression of Alzheimer disease. Not much is known about FRMD1 to date. Both FRMD1 and FRMD6 contains a single FERM domain which has a cloverleaf tripart structure composed of: (1) FERM_N (A-lobe or F1); (2) FERM_M (B-lobe, or F2); and (3) FERM_C (C-lobe or F3). The C-lobe is a member of the PH superfamily. The FERM domain is found in the cytoskeletal-associated proteins such as ezrin, moesin, radixin, 4.1R, and merlin. These proteins provide a link between the membrane and cytoskeleton and are involved in signal transduction pathways. The FERM domain is also found in protein tyrosine phosphatases (PTPs) , the tyrosine kinases FAK and JAK, in addition to other proteins involved in signaling. This domain is structurally similar to the PH and PTB domains and consequently is capable of binding to both peptides and phospholipids at different sites.

first ubiquitin-like (Ubl) domain located at the N-terminus of coronavirus SARS-CoV non-structural protein 3 (Nsp3) and related proteins; This ubiquitin-like (Ubl) domain (Ubl1) is found at the N-terminus of coronavirus Nsp3, a large multi-functional multi-domain protein which is an essential component of the replication/transcription complex (RTC). The functions of Ubl1 in CoVs are related to single-stranded RNA (ssRNA) binding and to interacting with the nucleocapsid (N) protein. SARS-CoV Ubl1 has been shown to bind ssRNA having AUA patterns, and since the 5'-UTR of the SARS-CoV genome has a number of AUA repeats, it may bind there. In mouse hepatitis virus (MHV), this Ubl1 domain binds the cognate N protein. Adjacent to Ubl1 is a Glu-rich acidic region (also referred to as hypervariable region, HVR); Ubl1 together with HVR has been called Nsp3a. Currently, the function of HVR in CoVs is unknown. This model corresponds to one of two Ubl domains in Nsp3; the other is located N-terminal to the papain-like protease (PLpro) and is not represented by this model.

FERM (Four.1 protein, Ezrin, Radixin, Moesin) domain, F1 sub-domain, found in tyrosine-protein phosphatase non-receptor type 13 (PTPN13); PTPN13, also termed Fas-associated protein-tyrosine phosphatase 1 (FAP-1), or PTP-BAS, or protein-tyrosine phosphatase 1E (PTP-E1 or PTPE1), or protein-tyrosine phosphatase PTPL1, belongs to the non-transmembrane FERM-containing protein-tyrosine phosphatase (PTP) subfamily characterized by a KIND domain, a FERM domain, five PDZ domains, and a C-terminal PTP catalytic domain. The FERM domain is made up of three sub-domains, F1, F2, and F3. This family corresponds to the F1 sub-domain, which is also called the N-terminal ubiquitin-like structural domain of the FERM domain (FERM_N). PTPN13 interacts with a variety of ligands, suggests an important role as a scaffolding protein. It is also involved in the regulation of apoptosis, cytokinesis and cell cycle progression.
