This expanded set of homologous sequences is then multiply-aligned using the profile as a template.
The second filter is likely to simultaneously remove more than one of these homologous sequences if it removes any at all.
Comparison of an un-annotated sequence to known homologous sequences is therefore a good starting point for predicting function.
Moreover, there is no murine sequence homologous to the alternative second exon of the human gene.
Collectively, the databases represent almost all public information on known genes, transcripts and relevant homologous sequences.
The homologous sequences of other representative members of this family are also shown.
The most common approach is the comparison of homologous sequences for genes using sequence alignment techniques to identify similarity.
It is a type of chromosomal crossover between homologous sequences that are not paired precisely.
At the C-terminal sequences 400-425, there is another sequence homologous to region 4.2.
For proteins, homologous sequences are typically grouped into families.
