Protein attributes

Sequence length	406 AA.
Sequence status	Complete.
Sequence processing	The displayed sequence is not processed.
Protein existence	Evidence at protein level.

General annotation (Comments)

Function	Single-stranded DNA binding protein that interacts with the region upstream of the C-myc gene. Binds specifically to the DNA sequence motif 5'-[AT]CT[AT][AT]T-3'. Probably has a role in DNA replication.
Subcellular location	Nucleus.
Tissue specificity	Highest amounts are found in placenta, lung and heart.
Developmental stage	Expressed at highest levels during the G1 to S transition of the cell cycle.
Sequence similarities	Contains 2 RRM (RNA recognition motif) domains.
Sequence caution	The sequence AAX93095.1 differs from that shown. Reason: Erroneous gene model prediction. The sequence CAA45923.1 differs from that shown. Reason: Erroneous initiation. Translation N-terminally extended. The sequence CAA45923.1 differs from that shown. Reason: Frameshift at positions 319 and 360.
