Protein attributes

Sequence length	1210 AA.
Sequence status	Complete.
Sequence processing	The displayed sequence is not processed.
Protein existence	Evidence at protein level.

General annotation (Comments)

Subcellular location	Nucleus Potential.
Involvement in disease	A chromosomal aberration involving AFF1 is associated with acute leukemias. Translocation t(4;11)(q21;q23) with MLL/HRX. The result is a rogue activator protein.
Sequence similarities	Belongs to the AF4 family.
Sequence caution	The sequence AAA36642.1 differs from that shown. Reason: Frameshift at positions 897, 905 and 1178.
