General annotation (Comments)

Function	Transcription factor which may be involved in neuroblastoma growth and malignant transformation. Favors nuclear targeting of ARID3A. Ref.5 Ref.6
Subunit structure	Heterodimer with ARID3A. Interacts with unphosphorylated RB1. Ref.1 Ref.6
Subcellular location	Nucleus Ref.1 Ref.6.
Tissue specificity	Expressed in placenta, testis and leukocytes. Expressed in neuroblastoma. Present in K-562 erythrocytic leukemia cell line (at protein level). Ref.1 Ref.5
Sequence similarities	Contains 1 ARID domain. Contains 1 REKLES domain.
Sequence caution	The sequence BAD92067.1 differs from that shown. Reason: Erroneous initiation. Translation N-terminally shortened.
