VIP21, a 21-kD membrane protein is an integral component of trans-Golgi- network-derived transport vesicles
It is proposed that VIP21, a cDNA encoding one protein of this complex, VIP21 (Vesicular Integral-membrane Protein of 21 kD), is a component of the molecular machinery of vesicular transport.
Prepeptide sequence of epidermin, a ribosomally synthesized antibiotic with four sulphide-rings
It is proposed that the N-terminus (–30 to –1) plays a cooperative role during modification reactions and prevents toxicity of the mature epidermin to the producing strain before the antibiotic is cleaved off and secreted.
Involvement of the Transmembrane Protein p23 in Biosynthetic Protein Transport
Specific release of membrane-bound annexin II and cortical cytoskeletal elements by sequestration of membrane cholesterol.
The biochemical and immunological observations indicate that the cortical cytoskeletal proteins alpha-actinin, ezrin and moesin, and membrane-associated actin are part of a complex containing annexin II and that stability of the complex is sensitive to cholesterol sequestering agents.
Gallidermin: a new lanthionine-containing polypeptide antibiotic.
The isolation procedures for gallidermin included adsorption directly from the culture broth, ion-exchange chromatography of the amphiphilic and basic polypeptide followed by desalting, and final purification by reversed-phase HPLC, which involved mainly a combination of automated gas-phase sequencing, thermospray liquid chromatography/mass spectrometry and fast-atom-bombardment mass spectromaetry.

It is speculated that VIP36 binds to sugar residues of glycosphingolipids and/or glycosylphosphatidyl‐inositol anchors and might provide a link between the extracellular/luminal face of glycolipid rafts and the cytoplasmic protein segregation machinery.
Interaction of glutamic-acid-rich proteins with the cGMP signalling pathway in rod photoreceptors
This work identifies GARPs as multivalent proteins that interact with the keyplayers of cGMP signalling, phosphodiesterase and guanylate cyclase, and with a retina-specific ATP-binding cassette transporter (ABCR), through four, short, repetitive sequences.

Negative factor (Nef) is a regulatory myristoylated protein of human immunodeficiency virus (HIV) that has a two-domain structure consisting of an anchor domain and a core domain separated by a…

The two major forms of sulfakinins were identified and chemically characterized from an extract of 800 corpora cardiaca/corpora allata complexes of the American cockroach, Periplaneta americana and were shown to be highly active on both the heart and hindgut.
