Protein attributes

Sequence length	1052 AA.
Sequence status	Complete.
Sequence processing	The displayed sequence is not processed.
Protein existence	Evidence at protein level.

General annotation (Comments)

Tissue specificity	Ubiquitously expressed. Overexpressed in malignant fibrous histiocytomas. Ref.1
Involvement in disease	A chromosomal aberration involving MFHAS1 may be a cause of B-cell lymphoma. Translocation t(8;14)(p23.1;q21) with a cryptic exon named '14q21 element'. The resulting fusion protein named 'chimeric MASL1' is tumorigenic in nude mice. Ref.3
Miscellaneous	Tumorigenic in nude mice.
Sequence similarities	Contains 13 LRR (leucine-rich) repeats. Contains 1 Roc domain.
