Limitation for the query sequence length for search on this site: 5000 residues in general; 3000 for tblastx.

The WU BLAST 2.08 family of programs includes:

blastp: compares an amino acid query sequence against a protein sequence database
blastn: compares a nucleotide query sequence against a nucleotide sequence database
blastx: compares a nucleotide query sequence translated in all reading frames against a protein sequence database
tblastn disabled due to limited CPU resources!: compares a protein query sequence against a nucleotide sequence database dynamically translated in all reading frames
tblastx: compares the six-frame translations of a nucleotide query sequence against the six-frame translations of a nucleotide sequence database. Please note that tblastx program cannot be used with the nr database on the BLAST Web page.
