Sfp1 is a multimodular protein composed of four subunits (Sfp1 Alpha, Beta, Delta, and Gamma) displaying different functional domains. We recombinantly produced two fragments of Sfp1 comprising most of its functional domains: the C-terminal part of the Beta subunit (rSfp1 Beta C-term) and the Delta subunit (rSfp1 Delta). Surface plasmon resonance analyses of protein adsorption onto different model surfaces showed that rSfp1 Beta C-term exhibits a significantly higher adsorption than the fibrinogen control on hydrophobic, hydrophilic protein-resistant, and charged self-assembled monolayers, while rSfp1 Delta adsorbed more on negatively charged and on protein-resistant surfaces compared to fibrinogen. Truncated recombinant rSfp1 Beta C-term proteins were produced in order to investigate the role of the different functional domains in the adsorption of this protein. The analysis of their adsorption capacities on glass showed that two mechanisms are involved in rSfp1 Beta C-term adsorption: (1) one mediated by the EGF-like domain and involving Ca<sup>2+</sup> and Mg<sup>2+</sup> ions, and (2) one mediated by the sequence of Sfp1 Beta with no homology with known functional domain in databases, in the presence of Na<sup>+</sup>, Ca<sup>2+</sup> and Mg<sup>2+</sup> ions.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"Disentangling the roles of functional domains in the aggregation and adsorption of the multimodular sea star adhesive protein Sfp1","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2026-06-05 01:31:27.597702","timezone_type":1,"timezone":"+02:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":"Sea stars; Adhesive protein; Sfp1; Functional domain; Adsorption; SPR","OtherDescriptors":null,"Notes":null,"AnaPub":2021,"MonPub":null,"DateUpdate":"2023-09-04","DateCreate":"2022-06-28","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":"WOS:000696152800001","VABBcode":null,"OpenAcc":0,"DOI":"10.1007/s10126-021-10059-y"},"refs":null,"anarec":{"AnaID":353191,"PubliDate":2021,"Pagination":"724-735","XtraPublOfAnaID":null,"ISBN":null,"Volume":"23","Issue":"5","BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":45426,"SerRR":"Marine Biotechnology.
