Homologous telomerase gene sequences

This group of patents – three of which are owned by Geron and University of Colorado (individually or jointly), one of which is co-owned by Geron and Albert Einstein College of Medicine, and one of which is owned by Research & Development Institute in Montana – concern nucleic acid sequences and gene products of telomerase from other species.  By no means does this group exhaust the species from which telomerase gene has been cloned; telomerase from other species can be found in the scientific literature.

The species represented in this group are:

Mouse telomerase reverse transcriptase

Claim 1:  An isolated, purified or recombinant polynucleotide encoding a telomerase reverse transcriptase protein, wherein said protein: (i) has at least 90% sequence identity to SEQ. ID NO:2; (ii) has telomerase catalytic activity when associated with telomerase RNA component; and (iii) contains at least one of the following amino acid motifs; Motif T: W-X12 -FFY-X1 -TE-X11 -R-X3 -W; Motif 1: LR-X1 -IPK; Motif 2: R-X1 -I-X15 -K; Motif A: P-X3 -F-X3 -D-X4 -YD; Motif B: Y-X4 -G-X2 -QG-X3 -S; Motif C: DD-X1 -L; or Motif D: A-X2 -F-X18 -K; wherein Xn is a sequence of unspecified amino acids of length “n”.

See Appendix 1 for complete list.

* – A terminal disclaimer was filed for this patent.  Without obtaining the full prosecution history of this patent to reveal which patent it was disclaimed in favor of, certainty of the expiry date is not possible.

[1] An interference is a procedure conducted by the United States Patent and Trademark Office when multiple applications have identical claims.  The purpose of an interference is to determine who was the first-in-time inventor and so deserves the patent.
