A central problem for 21st century science will be the annotation and
understanding of the human genome. My talk will be concerned with
topics within this area, in particular annotating pseudogenes (protein
fossils), binding sites, CNVs, and novel transcribed regions in the
genome. Much of this work has been carried out in the framework of the
ENCODE and modENCODE projects.
In particular, I will discuss how we identify regulatory regions and
novel, non-genic transcribed regions in the genome based on processing
of tiling array and next-generation sequencing experiments. I will
further discuss how we cluster together groups of binding sites and
novel transcribed regions.
Next, I will discuss a comprehensive pseudogene identification
pipeline and storage database we have built. This has enabled us to
identify >10K pseudogenes in the human and mouse genomes and analyze
their distribution with respect to age, protein family, and
chromosomal location. I will try to inter-relate our studies on
pseudogenes with those on transcribed regions. At the end I will bring
these together, trying to assess the transcriptional activity of
Throughout I will try to introduce some of the computational
algorithms and approaches that are required for genome annotation --
e.g., the construction of annotation pipelines, developing algorithms
for optimal tiling, and refining approaches for scoring microarrays.
