- 1. LAF4
- [Preferentially expressed in lymphoid tissues (highest in thymus) and encoded by human LAF4 Gene (LAF4/MLLT2 Family), 1227-amino acid 134-kD nuclear DNA-binding transcriptional activator Lymphoid Nuclear Protein 4 may function in lymphoid development and oncogenesis. Greatest similarity to MLLT2 occurs in the N-terminal and C-terminal regions. (from LocusLink, Swiss-Prot, OMIM, and NCI) ( NCI )] (UMLS (NCI) C0386006) =Amino Acid, Peptide, or Protein; Biologically Active Substance ;
| - 2. LAFB
- [An impairment of transmission of the cardiac electrical impulse along the fibers of the left anterior fascicle. In left anterior fascicular block (LAFB) the posteroinferior regions of the left ventricular endocardium are activated abnormally before the anterosuperior left ventricular area. After emerging from the posteroinferior division of the left bundle branch, the impulse first propagates in an inferior, rightward, and usually anterior direction for a short period of time. This orientation is responsible for the small q waves in leads I and aVL and for the r waves in leads II, III, and aVF. ( NCI )] (UMLS (NCI) C0264912) =Pathologic Function ;
