HTC

The HTC division of DDBJ contains draft sequence data derived from cDNA libraries created using full length insert cDNA (mRNA) cloning methods.
Like genome data (HTG), when sequences are considered to be finished level, the data will be moved from HTC to corresponding taxonomic division.

You can submit HTC data to DDBJ through Mass Submission System (MSS).

Notes on HTC/full length insert cDNA submission

Prior to your submission, remove regions of cloning vectors from your sequences.
Clone ID is required for clone qualifier.
It is strongly recommended to include qualifiers indicating expression conditions; tissue (tissue_type), developmental stage (dev_stage), mating type (mating_type or sex) and so on.
As mentioned above, HTC is different from EST assemble sequence. Do not confuse with TSA: Transcriptome Shotgun Assembly.

Aspects of HTC/full length insert cDNA

If the sequence is considered to be finished, LOCUS line provides the division name according to taxonomic lineage; either of “HUM”, “PRI”, “ROD”, “MAM”, “VRT”, “INV” or “PLN”.
If the sequence is not finished level, the DIVISION name is “HTC”.
If the sequence is considered to be finished, KEYWORDS line provides the keyword, “FLI_CDNA”.
If the sequence is not finished level, “HTC” is appeared as a keyword.
In HTC data, if the sequence is likely to be full length, it has a KEYWORDS, “HTC_FLI”.
Optionally, KEYWORDS line provides some methodological keyword, “oligo capping”, “CAP trapper” or the like.
