Fibril and hence the whole muscle. Elastin is a fibrous protein common in various soft tissues, like skin, blood vessels and lung tissue. Each monomer connects with each other, forming a 3D network, with ability to endure over 200% strain before deformation. Keratin is a structural protein mainly found in hair, nails, hooves, horns, quills. Basically keratin is formed by polypeptide chains, which coil into α-helices with sulfur cross-links or bond into β-sheets linked by hydrogen bonding. β-keratin, which is tougher than α-conformation, is more common in birds and reptiles. Resilin is an elastomeric insect protein, consisting of both α-helices and
Cleft lip and palate transmembrane protein 1 may belong to a new gene family. This family also contains the "Homo sapiens" cisplatin resistance related protein CRR9p which is associated with CDDP-induced apoptosis. Cleft lip and palate transmembrane protein 1 Cleft lip and palate transmembrane protein 1 is a protein that in humans is encoded by the "CLPTM1" gene. It belongs to a family of several eukaryotic cleft lip and palate transmembrane protein 1 sequences. Cleft lip with or without cleft palate is a common birth defect that is genetically complex. The nonsyndromic forms have been studied genetically using linkage and candidate-gene association studies with only partial success
