It also regulates its own UBC7-mediated degradation. MARCH6 interacts with ubiquitin-specific protease USP19, which deubiquitinates and stabilizes MARCH6 and inhibits p97-dependent proteasomal degradation. It is also involved in the cholesterol synthesis pathway by controlling the degradation of squalene monooxygenase (SM), and affects 3-hydroxy-3-methyl-glutaryl coenzyme A reductase (HMGCR). Furthermore, it may be a key regulator of thyroid hormone activation in a number of tissues, since it mediates the proteasomal degradation of type 2 iodothyronine deiodinase (D2). MARCH6 contains 14 transmembrane helices and a conserved N-terminal C4HC3-type RING-CH finger, also known as vRING or RINGv, a variant of C3H2C3-type RING-H2 finger, that catalyzes ubiquitin Lys48-specific ligation.

It is a functional homolog of Kaposi"s sarcoma associated-herpes virus encoded proteins, modulator of immune recognition (MIR) 1 and 2, which are involved in the evasion of host immunity. MARCH8 mediates the ubiquitination and down-regulation of immune regulatory cell surface molecules, including major histocompatibility complex class II (MHCII), CD86, transferrin receptor, HLA-DM, and Fas in immune cells. Moreover, MARCH8 controls cell surface expression of some additional proteins. It regulates the ubiquitination and lysosomal degradation of the transferrin receptor (TfR). Tumor necrosis factor-related apoptosis inducing ligand receptor 1 (TRAIL-R1) is also a physiological substrate of the endogenous MARCH8, which regulates the steady-state cell surface expression of TRAIL-R1. Meanwhile, it negatively regulates interleukin-1 (IL-1) beta-induced NF-kappaB activation by targeting the IL-1 receptor accessory protein (IL1RAP) coreceptor for ubiquitination and degradation. Furthermore, MARCH8 functions in the embryo to modulate the strength of cell adhesion by regulating the localization of E-cadherin. In addition, MARCH8 plays a role in the inhibition of inflammatory cytokine production, suggesting a new therapeutic approach to the treatment of rheumatoid arthritis (RA).

MARCH2 is a Golgi-localized, membrane-associated E3 ubiquitin-protein ligase that is involved in endosomal trafficking through the binding of syntaxin 6 (STX6). It is involved in the cystic fibrosis transmembrane conductance regulator (CFTR)-associated ligand (CAL)-mediated ubiquitination and lysosomal degradation of mature CFTR through the association with adaptor proteins CAL and STX6. It also reduces the surface expression of CD86 and the transferrin receptor TFRC and regulates cell surface carvedilol-bound beta2-adrenergic receptor (beta2ARs) expression. Moreover, MARCH2 interacts with and ubiquitinates PDZ domains polarity determining scaffold protein DLG1 through its PDZ-binding motif, suggesting it may function as a molecular bridge with ubiquitin ligase activity connecting endocytic tumor suppressor proteins such as syntaxins to DLG1. MARCH3 is an E3 ubiquitin-protein ligase that is broadly expressed at relatively high levels in spleen, colon, and lung. It is localized to early endosomes, binds to MARCH2 and syntaxin 6, and is involved in the regulation of vesicular trafficking and fusion of the transport vesicles in endosomes.

MARCH5 also mediates the cell cycle-dependent degradation of Mitofusin 1 (Mfn1) in G2/M phase, and thus serves as an upstream quality controller of Mitofusin 1 (Mfn1), preventing excessive accumulation of Mfn1 protein under stress conditions, which is crucial for mitochondrial homeostasis and cell viability. Moreover, MARCH5 is involved in maintaining mouse-embryonic stem cell (mESC) pluripotency via suppression of ERK signalling. It is also a positive regulator of Toll-like receptor 7 (TLR7)-mediated NF-kappaB activation in mammals.

RING-CH finger, H2 subclass (C4HC3-type), found in membrane-associated RING-CH4 (MARCH4); MARCH4, also known as membrane-associated RING finger protein 4, membrane-associated RING-CH protein IV (MARCH-IV), or RING finger protein 174 (RNF174), is a transmembrane E3 ubiquitin-protein ligase that down-regulates the tetraspanin CD81 and major histocompatibility complex-I (MHC). It also associates with Mult1, suppressing Mult1 expression at the cell surface in a lysine-dependent manner that can be reversed by heat shocking the cells. MARCH4 contains an N-terminal C4HC3-type RING-CH finger, also known as vRING or RINGv, a variant of C3H2C3-type RING-H2 finger, followed by two transmembrane regions.

RING-CH finger, H2 subclass (C4HC3-type), found in membrane-associated RING-CH9 (MARCH9); MARCH9, also known as membrane-associated RING finger protein 9, membrane-associated RING-CH protein IX (MARCH-IX), or RING finger protein 179 (RNF179), is a transmembrane E3 ubiquitin-protein ligase that down-regulates Mult1, CD4, major histocompatibility complex-I (MHC), and intercellular adhesion molecule (ICAM-1). It may also interact with receptor-type protein-tyrosine phosphatases (e.g. PTPRJ/CD148) as well as Fc gamma receptor IIB (CD32B), HLA-DQ, signaling lymphocytic activation molecule (CD150), and polio virus receptor (CD155). MARCH9 contains an N-terminal C4HC3-type RING-CH finger, also known as vRING or RINGv, a variant of C3H2C3-type RING-H2 finger, followed by two transmembrane regions.

RING-CH finger, H2 subclass (C4HC3-type), found in membrane-associated RING-CH2 (MARCH2); MARCH2, also known as membrane-associated RING finger protein 2, membrane-associated RING-CH protein II (MARCH-II), or RING finger protein 172 (RNF172), is a Golgi-localized, membrane-associated E3 ubiquitin-protein ligase that is involved in endosomal trafficking through the binding of syntaxin 6 (STX6). It is involved in the cystic fibrosis transmembrane conductance regulator (CFTR)-associated ligand (CAL)-mediated ubiquitination and lysosomal degradation of mature CFTR through the association with adaptor proteins CAL and STX6. It also reduces the surface expression of CD86 and the transferrin receptor TFRC and regulates cell surface carvedilol-bound beta2-adrenergic receptor (beta2AR) expression. Moreover, MARCH2 interacts with and ubiquitinates PDZ domains polarity determining scaffold protein DLG1 through its PDZ-binding motif, suggesting it may function as a molecular bridge with ubiquitin ligase activity connecting endocytic tumor suppressor proteins such as syntaxins to DLG1. MARCH2 contains a C4HC3-type RING-CH finger, also known as vRING or RINGv, a variant of C3H2C3-type RING-H2 finger, in the N-terminal cytoplasmic region, two transmembrane domains in the middle region, and a PDZ-binding motif at the C-terminus.

H2 subclass of RING (RING-H2) fingers and its variants; The RING finger is a specialized type of Zn-finger of 40 to 60 residues that binds two atoms of zinc. It is defined by the "cross-brace" motif that chelates zinc atoms by eight amino acid residues, typically Cys or His, arranged in a characteristic spacing. Canonical RING motifs have been categorized into two major subclasses, RING-HC (C3HC4-type) and RING-H2 (C3H2C3-type), according to their Cys/His content. There are also many variants of RING fingers: some have different Cys/His patterns while some lack a single Cys or His residue at typical Zn ligand positions (the fourth or eighth zinc ligand is prevalently exchanged for an Asp, which can indeed chelate Zn in a RING finger as well). This family corresponds to the H2 subclass of RING (RING-H2) finger proteins that are characterized by containing C3H2C3-type canonical RING-H2 fingers or noncanonical RING-H2 finger variants, including C4HC3- (RING-CH alias RINGv), C3H3C2-, C3H2C2D-, C3DHC3-, and C4HC2H-type modified RING-H2 fingers. The canonical RING-H2 finger has been defined as C-X2-C-X(9-39)-C-X(1-3)-H-X(2-3)-H-X2-C-X(4-48)-C-X2-C, X is any amino acid and the number of X residues varies in different fingers. It binds two Zn ions in a unique "cross-brace" arrangement, which distinguishes it from tandem zinc fingers and other similar motifs. RING-H2 finger can be found in a group of diverse proteins with a variety of cellular functions, including oncogenesis, development, viral replication, signal transduction, the cell cycle and apoptosis. Many of them are ubiquitin-protein ligases (E3s) that serves as a scaffold for binding to ubiquitin-conjugating enzymes (E2s, also referred to as ubiquitin carrier proteins or UBCs) in close proximity to substrate proteins, which enables efficient transfer of ubiquitin from E2 to the substrates.
