Abstract
The present invention relates to novel epidermal protein, sciellin. Sciellin polypeptides comprise an N-terminal domain, a central domain containing sixteen repeats and a C-terminal LIM domain. Sciellin polypeptides may function as precursors of the cornified envelope of keratinizing tissues. Described herein are isolated and antisense nucleic acids molecules, recombinant expression vectors, host cells and non-human transgenic animals containing an insertion or a disruption of the sciellin gene. Diagnostic, screening and therapeutic methods utilizing the compositions of the invention are also provided.
Claims17
A substantially pure nucleic acid comprising a nucleotide sequence which is at least 90% identical to the nucleotide sequence of SEQ ID NO:1, wherein the nucleic acid encodes a protein that (a) forms homotrimeric beta helices;
- (b) comprises a LIM domain;
- and (c) has a molecular weight between about 75.3 and 86.2 kDa.
A substantially pure nucleic acid comprising the nucleotide sequence of SEQ ID NO:1.
A nucleic acid that hybridizes under high stringency conditions to the full complement of the nucleotide sequence of SEQ ID NO:1.
A substantially pure nucleic acid which encodes a fragment of SEQ ID NO:2 of at least 50 amino acids in length.
A substantially pure nucleic acid which encodes an amino acid sequence which is at least 90% identical to the amino acid sequence of SEQ ID NO:2, wherein the nucleic acid encodes a protein that (a) comprises a LIM domain;
- (b) forms homotrimeric beta helices;
- and (c) has a molecular weight between about 75.3 and 86.2 kDa.
A substantially pure nucleic acid encoding the sciellin polypeptide of SEQ ID NO:2.
A substantially pure nucleic acid which encodes a fragment of the amino acid sequence of SEQ ID NO:2, wherein the fragment comprises a LIM domain.
A substantially pure nucleic acid which encodes a fragment of the amino acid sequence of SEQ ID NO:2, wherein the fragment comprises a domain capable of forming a homotrimeric beta-helix.
