BEL1

Gene
BEL1
Protein
Homeobox protein BEL1 homolog
Organism
Arabidopsis thaliana
Length
611 amino acids
Function
Plays a major role in ovule patterning and in determination of integument identity via its interaction with MADS-box factors. Formation of complex with AG-SEP dimers negatively regulates the carpel identity process and favors the maintenance of ovule identity. BEL1-STM complex maintains the indeterminacy of the inflorescence meristem. Required, with SPL, for cytokinin-induced PIN1 expression in ovules (PubMed:22786869).
Similarity
Belongs to the TALE/BELL homeobox family.

Organism
Simian foamy virus type 1
Length
308 amino acids
Function
Transcriptional transactivator that activates the viral internal promoter (IP), thereby enhancing its own expression. This transactivation is repressed by nuclear factor I. Also transactivates the long terminal repeat (LTR) promoter, thereby inducing structural gene expression, initiating the late phase of infection. It is therefore a key regulator of viral gene expression. It directly binds to and activates DNA target sites of viral promoters and those of distinct cellular genes. Required for viral replication (By similarity).
