AT-rich element binding factor 1 (ATBF1) mRNA encodes a transcription facto
r implicated in neuronal differentiation. A cDNA for the protein that can b
ind the 5'-noncoding sequence of the ATBF1 mRNA was cloned. The deduced pro
tein, termed SRL300, contains a unique RNA-binding region, two large RS dom
ains and many phosphorylation sites. SRL300 protein was detected in both hu
man and rat cells. (C) 2000 Elsevier Science B.V. All rights reserved.
