New Homepage

Welcome to the new ChromDB homepage. We will be featuring ChromDB tools and reports in this space for our future updates. For this update we are focusing on the types of sequences and organisms presented displayed at ChromDB. Three types of sequences are included in the database: genomic-based (predominantly plant sequences); transcript-based (EST contigs or cDNAs for plants lacking a sequenced genome); and NCBI RefSeq sequences for a variety of model animal organisms. The Gene Record Page for any sequence indicates the type of sequence. Click on the names of the organisms presented below to see examples of these sequences.


Genomic-based Transcript-based RefSeq-based
Corn (Zea mays) Wheat (Triticum aestivum) Zeke (Homo sapiens)

New Protein Group Releases:
Dek group: The human DEK protein is an abundant chromatin protein that is linked with cancers and autoimmune disease. Hu et al. 2007 (PMID: 17524367) have shown DEK accumulates at promoter/enhancers of some actively transcribed genes but is mostly excluded from heterochromatin. DEK homologous sequences are found in plants, but these proteins lack the Pfam SAP domain found in the animal proteins.

Request for questions:
We want to accumulate a series of frequently asked questions to aid users in navigating through the website and using the ChromDB tools. Please submit questions to the FAQ link

Upcoming releases: We are currently analyzing predicted proteins for Sorghum bicolor and Selaginella moellendorffii. We will release these annotations after we finish our intial analyses to check the accuracy of the predicted models from the Joint Genome Institute.
