Protein attributes

Sequence length	356 AA.
Sequence status	Complete.
Protein existence	Evidence at protein level

General annotation (Comments)

Function	Single-stranded nucleic acid binding protein that binds preferentially to oligo dC.
Subcellular location	Nucleus. Cytoplasm. Note: Loosely bound in the nucleus. May shuttle between the nucleus and the cytoplasm.
Tissue specificity	Abundantly expressed in skeletal muscle, thymus and peripheral blood leukocytes while a lower expression is observed in prostate, spleen, testis, ovary, small intestine, heart, liver, adrenal and thyroid glands.
Post-translational modification	Phosphorylated; lowers poly(rC)-binding activity. Ref.6 Ref.7 Ref.8 Ref.9 Ref.10 Ref.11 Ref.12 Ref.13 Ref.14 Ref.15 Ref.16 Ref.17
Sequence similarities	Contains 3 KH domains.
Sequence caution	The sequence CAA82631.1 differs from that shown. Reason: Frameshift at position 301.
