This family consists of several ribosome associated membrane protein RAMP4 (or SERP1) sequences. Stabilisation of membrane proteins in response to stress involves the concerted action of a rescue unit in the ER membrane comprised of SERP1/RAMP4, other components of the translocon, and molecular chaperones in the ER. Length = 63
>PF06624 RAMP4: Ribosome associated membrane protein RAMP4; InterPro: IPR010580 This entry contains Serp1/Ramp4, which has been shown to interacts with target proteins during their translocation into the lumen of the endoplasmic reticulum
It has also been shown to protect unfolded target proteins against degradation during ER stress. It may facilitate glycosylation of target proteins after termination of ER stress and may modulate the use of N-glycosylation sites on target proteins [, ].
>PF06724 DUF1206: Domain of Unknown Function (DUF1206); InterPro: IPR009597 This region consists of two a pair of transmembrane helices and occurs three times in each of the family member proteins
>PF10661 EssA: WXG100 protein secretion system (Wss), protein EssA; InterPro: IPR018920 The Wss (WXG100 protein secretion system) in Staphylococcus aureus seems to be encoded by a locus of eight ORFs, called ess (eSAT-6 secretion system) []
This locus encodes, amongst several other proteins, EssA, a protein predicted to possess one transmembrane domain. Due to its predicted membrane location and its absolute requirement for WXG100 protein secretion, it has been speculated that EssA could form a secretion apparatus in conjunction with YukC and YukAB. Proteins homologous to EssA, YukC, EsaA and YukD were absent from mycobacteria []. Members of this family are associated with type VII secretion of WXG100 family targets in the Firmicutes, but not in the Actinobacteria. This highly divergent protein family consists largely of a central region of highly polar low-complexity sequence containing occasional LF motifs in weak repeats about 17 residues in length, flanked by hydrophobic N- and C-terminal regions.
