<p>This subsection of the 'Family and domains' section provides general information on the biological role of a domain. The term 'domain' is intended here in its wide acceptation, it may be a structural domain, a transmembrane region or a functional domain. Several domains are described in this subsection.<p><a href='/help/domain_cc' target='_top'>More...</a></p>Domaini

The transmembrane domain 1 and 2 function as a signal-anchor and stop-transfer sequence, respectively, generating a double-spanning integral membrane protein with a N- and C-terminal cytoplasmic orientation. Transmembrane domain 1 and 2 are probably sufficient to mediate membrane translocation and topology formation in a N-myristoylation-independent manner. Transmembrane domain 2 is sufficient to block the protein secretion pathway. The two coiled-coil domains are necessary for its endoplasmic reticulum (ER) three-way tubular junction localization. The C4-type zinc finger motif is necessary both for its ER three-way tubular junction localization and formation.By similarity
