Alu Sequence Database
		    (last update 10/13/88 - D.K.)

In addition to this documentation file, alu.doc, two data files are
available: alu.js and alu-js.seq.  The file alu.js contains aligned
Alu sequences as explained in the note below.  The file alu-js.seq
contains the raw sequence data in IntelliGenetics format.  Alignment
gaps have been removed in the alu-js.seq file, and, when multiple
sequences occur in the same LOCUS name, e.g., HUMTPA, they have been
renamed HUMTPA-2, HUMTPA-3, etc., to facilitate their use with the IG
software on BIONET.  The following note is from the authors.  Dr.
Jurka, formerly of the MBCRR, is currently the BIONET Scientist at the
BIONET Resource.

Dear Colleague,

These are Alu sequences used in study by Jerzy Jurka (Yurek Yurka)
and Temple Smith, published in Proc. Natl. Acad. Sci. USA
85: 4775-4778 (1988). The sequences have been aligned by hand 
using sequence editor - MASE (Faulkner, D.V. and Jurka, J.
TIBS 13: 321-322, 1988). The enclosed file is in the aligned
output format useful for 'by eye' analysis. If you need MASE-input 
version of this file, please contact jurka@bionet-20.arpa.
All non-profit researchers can obtain MASE software free of charge
from Susan Russo (617) 732-3746. Address: MBCRR, J-815, Dana-Farber
Cancer Institute, 44 Binney Street, Boston MA, 02115.

The sequence-types are the following: 1- Consensus Alu (equivalent
to Alu-S); 2-33 Alu-J; 34-102 branch 'a' of Alu-S (Alu-a), which
most likely consists of 2 separate branches tentatively called
Alu-d and Alu-e (see the paper); 103-113 Alu-c and 114-125 Alu-b.

Yours sincerely,
Jerzy Jurka
Temple Smith
