NRCD Human Full-Length cDNA Clone

NRCD Human Full-Length cDNA Clones

The RIKEN BioResource Center is distributing copies of full-length human cDNA clones that were produced by Dr. Seishi Kato of the Research Institute of National Rehabilitation Center for Persons with Disabilities to collect an entire set of full-length cDNA clones derived from human retina-derived cell lines. Approximately 39,000 clones corresponding to 7,067 genes are available.

Property of these libraries:
(1) The libraries containing sequences from their cap site to their poly(A) tail
Because cDNA produced from capped mRNA by the V-Capping Method has an additional dGMP (G) at its 5' end, we can validate full-length cDNA by the presence of an additional G at that terminal (Kato, S. et al., 2005).
(2) Few occasions of nucleotide substitution and deletion
Because the V-Capping Method lacks a PCR step and an amplification step, errors of nucleotide substitution and deletion produced in the steps are few occasions.
(3) The libraries containing cDNA derived from rare genes and long transcript
Because the V-Capping Method lacks a PCR step and an amplification step, gene expression levels and transcript size are no longer caveats in the making of cDNA libraries. These cDNA libraries constructed from ARPE-19 and Y79 cells contained many long (more than 7 kbp) cDNA clones (Kato, S. et al., 2005; Oshikawa, M. et al., 2008, 2011). The length of the longest cDNA was approximately 13 kbp (Oshikawa, M. et al., 2011).
(4) The libraries containing many variants of cDNA
Because gene expression levels and transcript size are no longer caveats in the making of cDNA libraries by the V-Capping Method, these libraries contain many variant cDNAs from the same gene locus by alternative promoter usage, diverse transcriptional initiation, alternative splicing, and alternative polyadenylation (Oshikawa, M. et al., 2008, 2011).
(5) The clones containing unidirectional cDNA as an insert fragment
The V-Capping Method enables us a unidirectional cDNA cloning, and the cDNAs for an antisense gene can be assured (Oshikawa, M. et al., 2008, 2011).

Source of RNA:
AR Library: human retinal pigment epithelium cell line, ARPE-19 (CRL-2302, ATCC)
RB Library: human retinoblastoma cell line, Y79 (HTB-18, ATCC)

Method of Generation of Full-Length cDNA:
Vector-Capping Method (V-Capping Method, Kato, S. et al., 2005, 2011)

Vector Backbone:
The following vectors derived from pKA1 (Kato, S. et al, 1994)
pKA1U5 (accession no. AB191256 (map), Kato, S. et al., 2005)
pGCAP1 (accession no. AB191257 (map), Kato, S. et al., 2005)
pGCAP10 (accession no. AB371573 (map), Oshikawa, M. et al., 2008)

Property of the 5' terminal region of full-length cDNA:
Boundary region of vectors (lower case) and full-length cDNA (capital letter) is indicated. One G (indicated by red character) is inserted between the vector sequence and 5' terminal of cDNA. In some case, some nucleotide (single or multiple T, or single G in many case) is inserted before G (Kato, S. et al., 2005). During synthesis of the first strand cDNA from vector primers, some nucleotide sequences were not removed well because of an insufficient digestion by restriction enzymes (Kato, S. et al., 2011). The NotI recognition site is placed downstream of poly(A) site.
