“Background C. albicans SUR7 shares 44% identity and 65% similarity with S. cerevisiae SUR7. S. cerevisiae SUR7 encodes a predicted integral membrane protein with an N-terminal AZD1152 price signal sequence and four transmembrane domains, and is a member of a family of proteins that also includes Yn1194p, Ydl222p, and Ylr414cp [1, 2]. Sur7p localizes to large, immobile, stable cortical patches on the plasma membrane, termed “”eisosomes”" which mark sites

of endocytosis [3, 4]. Deletion of S. cerevisiae SUR7 resulted in a strain with a defect in sporulation and altered plasma membrane sphingolipid content [4]. Alvarez and Konopka [5] identified C. albicans Sur7p in a detergent-resistant fraction of the plasma membrane in a proteomics study on N-acetylglucosamine-induced buy Everolimus proteins. Recently, they generated a C. albicans sur7Δ knockout mutant which is characterized by aberrant cell wall organization [2]. Specifically, lack of SUR7 in C. albicans results in mislocalization of actin and septin, and abnormal cell wall material protruding into and forming structures within the cytoplasm. However, from a phenotypic standpoint, little is known

regarding the role of C. albicans SUR7 in pathogenesis. A number of C. albicans virulence-related secreted proteins that remain associated with the plasma membrane or cell wall have been identified, including the outer mannoprotein Hwp1p [6], adhesins encoded by the ALS family of genes [7], and membrane proteins encoded by the Palbociclib pH-responsive genes PHR1 and PHR2 [8–11]. However, a genome-wide understanding of Candida secretory pathway proteins and virulence is still limited. Previously, we took advantage of SignalP v2.0 [12, 13] and a series of additional validated predictive algorithms to define a computational secretome of C. albicans from its entire genome [14]. In addition to identifying putative soluble secretory proteins, we also identified a number of putative and known membrane and cell-wall associated proteins [14]. We next compared these databases with published genome-wide expression profiling data to identify candidate virulence-related genes.
